What are my Chances of Getting Pregnant on Different Types of Birth Control?

There are many different types of birth control, and each has its own set of pros and cons when it comes to pregnancy prevention. In this guide, you’ll learn about the effectiveness of various types of birth control and how they compare to one another, plus important things to consider before you choose your birth control method.


Birth Control Pill


The birth control pill is one of your most reliable forms of contraception, though it’s not perfect. For example, women who are overweight or obese have a slightly higher risk for getting pregnant while taking oral contraceptives. In addition, about 9 in 100 women may become pregnant in a year of starting oral contraceptives. Most unplanned pregnancies happen because couples fail to use contraception properly; if you’re at high risk for pregnancy (if you haven’t gone through menopause), take your pills more than three hours apart or skip them altogether and you may be at increased risk.


Male Condom


The male condom is one of the oldest forms of birth control and can provide a nice level of protection from pregnancy. However, it’s not completely foolproof—it’s possible to break, come off or have an accidental slippage during intercourse. If you use condoms for birth control, you have about a 15 percent chance (or higher) of getting pregnant in any given year. That said, if you're only having unprotected sex once every few months, that might be enough protection for your needs. In addition to birth control benefits, condoms also offer protection against sexually transmitted diseases and even HIV. Most health insurance plans cover condoms with no additional cost after age 18. Keep in mind that not all brands work equally well—some may break more easily than others.


Intrauterine Device (IUD)


Intrauterine devices (IUDs) are small, T-shaped devices inserted into your uterus by a health care provider that prevent pregnancy. There are two kinds of IUDs available in the United States: Paragard and Mirena. Paragard is a copper IUD, which means it contains no hormones. Because Paragard doesn’t contain hormones, it doesn’t protect against HIV/AIDS or other STDs and you should use condoms to reduce your risk for contracting an STD if you choose to use Paragard as birth control. If you want to avoid hormonal side effects, Mirena is a good option because it uses a low dose of progesterone. As with all forms of birth control, using an IUD does not guarantee that you won’t get pregnant. But studies show that less than 1 percent of women who have had their IUDs inserted become pregnant within one year of having it put in place. The American College of Obstetricians and Gynecologists recommends considering getting an IUD if you are looking for long-term protection from pregnancy but don't want to take daily medication or have surgery.


The Shot (Depo-Provera)


Depo-Provera is a long-lasting injectable contraceptive that’s given once every three months. It prevents pregnancy by stopping ovulation, thickening cervical mucus and lowering sperm count. The shot has been proven to be one of the most effective forms of birth control (the CDC says it’s 99 percent effective when used perfectly). The key word there is perfectly—it can be less effective when women don’t get their shots at a regular interval or fail to remember to use backup birth control immediately after getting their shots. What are your chances if you do it wrong? According to the CDC, about seven out of 100 women will become pregnant each year while using Depo-Provera as their only form of contraception. That number jumps up to 10 out of 100 for those who aren’t getting their shots regularly.

Knowledge is Key

So there you have it. Condoms and birth control methods like Depo-Provera offer women extremely effective contraception, and can prevent unplanned pregnancies if they’re used correctly. However, they can’t prevent them 100% of the time—unprotected sex is always a risk with condoms, just as it is with birth control pills. In many ways, modern contraceptives bring us closer to our goal of lowering unplanned pregnancy rates. Make sure you do your research about your particular method of choice and make an appointment with ACPC Women's Clinic or pharmacist about any questions or concerns you might have.

Pregnancy is a life-changing experience, but complications can arise that require immediate medical attention. One such complication is an ectopic pregnancy, a condition that affects approximately 1 in 50 pregnancies. Understanding the causes, symptoms, and treatment options can help women seek timely medical care and prevent life-threatening complications. What Is an Ectopic Pregnancy? An ectopic pregnancy occurs when a fertilized egg implants outside the uterus, most commonly in the fallopian tube. However, implantation can also occur in the ovary, abdominal cavity, or cervix. Because these locations are not designed to support a growing embryo, an ectopic pregnancy cannot proceed normally and requires medical intervention. Causes and Risk Factors While ectopic pregnancies can happen to anyone, certain factors increase the risk: Previous ectopic pregnancy – A history of ectopic pregnancy increases the likelihood of recurrence. Pelvic inflammatory disease (PID) – Infections like chlamydia or gonorrhea can cause scarring in the fallopian tubes. Tubal surgery – Previous surgeries on the fallopian tubes can lead to blockages or scarring. Endometriosis – This condition can cause tissue growth that affects the movement of the fertilized egg. Use of fertility treatments – Assisted reproductive technologies, such as in vitro fertilization (IVF), can slightly increase the risk. Smoking – Studies suggest that smoking may interfere with the function of the fallopian tubes. Symptoms of an Ectopic Pregnancy Ectopic pregnancies often present symptoms similar to those of a normal pregnancy, making early detection challenging. Common symptoms include: Abdominal or pelvic pain – Often sharp and concentrated on one side Vaginal bleeding – Light spotting or heavier bleeding unrelated to menstruation Shoulder pain – A sign of internal bleeding that irritates the diaphragm Dizziness or fainting – May indicate blood loss and shock in severe cases If you experience any of these symptoms, especially with a positive pregnancy test, seek medical attention immediately. Diagnosis and Treatment Doctors diagnose ectopic pregnancy through blood tests to measure hCG (pregnancy hormone) levels and ultrasounds to locate the pregnancy. If an ectopic pregnancy is confirmed, treatment options include: Medication (Methotrexate): If detected early, doctors may prescribe methotrexate to stop the embryo from growing and allow the body to absorb the tissue naturally. Surgery: If the pregnancy is advanced or causing internal bleeding, laparoscopic surgery may be required to remove the ectopic tissue and, in some cases, the affected fallopian tube. Emotional and Physical Recovery Recovering from an ectopic pregnancy can be both physically and emotionally challenging. While the physical recovery time varies, many women experience grief and loss. Seeking support from loved ones, counseling, or support groups can be helpful. Can You Get Pregnant Again? Having an ectopic pregnancy does not mean you cannot conceive in the future. Many women go on to have healthy pregnancies, though the risk of another ectopic pregnancy is higher. Consulting a doctor before trying to conceive again can help assess risks and plan for a healthy pregnancy. Ectopic pregnancy is a serious but treatable condition. Awareness of the risk factors, symptoms, and treatment options can help ensure early detection and appropriate medical care. If you suspect you may have an ectopic pregnancy, seeking prompt medical attention could be life-saving.

Making a pregnancy decision is deeply personal and can feel overwhelming. If you’re considering the abortion pill, it’s essential to be fully informed about the process, risks, and alternatives. At ACPC Women's Clinic, we’re here to provide clarity, support, and non-judgmental guidance. Before taking the abortion pill, here are five key things to consider: 1. Confirm Your Pregnancy Before making any decisions, it’s crucial to confirm that you are indeed pregnant. A medical-grade pregnancy test and an ultrasound can determine how far along you are, which affects your options. The abortion pill is only FDA-approved for use up to 10 weeks of pregnancy, so knowing your gestational age is vital. Additionally, an ultrasound can help detect an ectopic pregnancy, a life-threatening condition that requires immediate medical attention and cannot be treated with the abortion pill. Our clinic offers free pregnancy tests and ultrasounds to provide accurate information and ensure your safety. 2. Understand the Process and Risks The abortion pill, also known as medication abortion, involves two drugs: mifepristone and misoprostol . Mifepristone works by blocking progesterone, a hormone necessary for maintaining pregnancy, while misoprostol induces uterine contractions to expel the pregnancy. While the process is typically completed at home, it can be accompanied by significant cramping, heavy bleeding, nausea, fever, and other side effects. It’s important to be aware of potential risks, including incomplete abortion, which may require surgical intervention, severe bleeding, or infection. Additionally, some women experience emotional and psychological effects after an abortion. Speaking with a healthcare provider about these risks can help you make a well-informed decision. 3. Know Your Legal Rights and Protections Laws regarding abortion vary by state, and Colorado has specific regulations surrounding abortion access. Unlike some states, Colorado does not have a waiting period or parental consent requirement for minors, meaning women can obtain an abortion without mandatory delays. However, it’s essential to be aware of your rights and any potential legal implications of obtaining abortion pills online or across state lines. Some sources selling abortion pills online may not provide FDA-approved medications, increasing the risk of complications. 4. Explore All Your Options You deserve to know all of your options before making a final decision. We recommend utilizing our Health & Safety Informed Decision Checklist which answers frequently asked questions about abortion. Beyond abortion, adoption and parenting are also possibilities . While it may seem overwhelming, many resources exist to support women facing unintended pregnancies. Parenting support services, financial assistance programs, and adoption mentoring are available to help women make a decision that aligns with their values and long-term goals. Speaking with a trained advocate can help you explore what’s best for your unique situation without pressure or judgment. ACPC Women's Clinic provides confidential mentoring, educational resources, and referrals to services that can support you. 5. Seek Emotional and Medical Support An unintended pregnancy can bring emotional and physical challenges. Having a strong support system—whether it’s a counselor, trusted friend, or medical professional—can make a difference in coping with the emotional impact of your decision. Some women report experiencing feelings of relief after an abortion, while others struggle with emotions such as sadness, guilt, or regret. Seeking post-abortion counseling and emotional support can help process these feelings and ensure mental well-being. Our clinic provides confidential consultations and resources to help you make an informed decision and receive the care you need. No matter what decision you are facing, you are not alone. ACPC Women's Clinic is here to offer compassionate care and a safe space to discuss your options. Whether you need medical information, emotional support, or practical assistance, we are here to walk alongside you. If you have questions or need support, reach out to us today. Your health and well-being matter, and we are here to help you navigate this journey with clarity and confidence.

Pregnancy is a time of significant changes and considerations, especially regarding health and nutrition. One common question that arises is whether to continue or discontinue Vitamin D supplements during pregnancy. Vitamin D is crucial for various bodily functions, but its role becomes even more critical during pregnancy. Here’s a comprehensive look at why you should not stop taking Vitamin D supplements when you’re expecting. The Importance of Vitamin D during Pregnancy Bone Health for Mother and Baby: Vitamin D plays a vital role in calcium absorption, essential for the development of your baby's bones and teeth. Adequate Vitamin D levels help prevent rickets in newborns, a condition that leads to soft and weak bones. For the mother, maintaining proper Vitamin D levels can reduce the risk of osteoporosis and bone fractures. Immune System Support: Vitamin D is known to support the immune system. During pregnancy, a robust immune system is crucial to protect both the mother and the developing baby from infections and illnesses. Reduced Risk of Complications: Adequate Vitamin D levels during pregnancy have been associated with a lower risk of complications such as preeclampsia, gestational diabetes, and preterm birth. Ensuring sufficient intake can contribute to a smoother pregnancy journey. Mental Health Benefits: There is growing evidence suggesting that Vitamin D may play a role in mood regulation and the prevention of depression. Considering the emotional and psychological changes during pregnancy, maintaining adequate Vitamin D levels could be beneficial for mental well-being. Current Recommendations and Guidelines Medical professionals generally recommend that pregnant women maintain an adequate level of Vitamin D. The exact dosage can vary, but many health organizations suggest that pregnant women should aim for a daily intake of 600-800 IU (International Units) of Vitamin D. However, some women might need more based on their individual health conditions, skin pigmentation, geographic location, and dietary intake. Sources of Vitamin D Sunlight: The body can produce Vitamin D when the skin is exposed to sunlight. However, factors like geographic location, season, and sunscreen use can affect Vitamin D synthesis from sunlight. Diet: Foods like fatty fish (salmon, mackerel), fortified milk, eggs, and cheese are good dietary sources of Vitamin D. However, it can be challenging to obtain adequate amounts from diet alone. Supplements: Given the challenges of obtaining enough Vitamin D from sunlight and diet, supplements can be an effective way to ensure you meet your daily needs. Consulting with Your Healthcare Provider Before making any changes to your supplement regimen, it's crucial to consult with your healthcare provider. They can assess your current Vitamin D levels through a blood test and determine the appropriate dosage for your specific needs. Your healthcare provider can also provide guidance on the best type of supplement to take and monitor your levels throughout your pregnancy. Conclusion In summary, stopping Vitamin D supplements during pregnancy is generally not advisable without consulting your healthcare provider. Vitamin D plays a crucial role in the health of both mother and baby, supporting bone development, immune function, and reducing the risk of complications. Ensuring you have adequate Vitamin D levels can contribute to a healthier and more comfortable pregnancy. Always consult with your healthcare provider to tailor the best plan for your nutritional needs during this important time. By staying informed and proactive about your Vitamin D intake, you can help ensure a healthy pregnancy for you and your baby.
