Am I Safe? Concerns About Pregnancy While on Birth Control - Obstetrics and Gynecology

Is this safe? Or will it result in pregnancy?


Hello, doctor.
I have been taking the oral contraceptive pill (Yueh-Chi) and have just finished my third pack (which is also the third month).
For the first two months, I consistently had my withdrawal bleed four days after stopping the pill, and it would start on the fifth day! However, this month I have not been taking the pills at the same time; occasionally, I take them half an hour to an hour late (but never more than an hour late).
Today is the second day after stopping the pill, and I had intimate relations with my boyfriend today.
We used a condom, but when we finished and I tried to remove it, I found that the condom was at the entrance of my vagina! I checked with water, and it did not break, but I am worried that semen might have flowed into or come into contact with my vagina.
Is there a chance I could become pregnant? Or since I have been on the pill for three months, am I considered stable? Thank you for your response.
🙇‍♀️

When it comes to concerns about pregnancy while on birth control, particularly with the use of oral contraceptives and condoms, it's essential to understand how these methods work and their effectiveness in preventing pregnancy.

First, let's address the use of oral contraceptives. You mentioned that you have been taking the birth control pill (Yaz) for three months and have been consistent with it, although you noted some instances of taking it a little later than usual. Generally, as long as you take your pill within a three-hour window of your usual time, the effectiveness of the pill remains intact. The primary function of birth control pills is to prevent ovulation, and they also thicken cervical mucus to block sperm from reaching an egg. When taken correctly, the effectiveness of birth control pills is over 99%.

Now, regarding your recent experience with the condom. You indicated that during intimate relations, the condom was found at the vaginal opening after intercourse. This situation can be concerning, but it's important to evaluate a few factors:
1. Condom Integrity: You mentioned that you checked the condom for breaks and found none. This is a good sign, as a compromised condom can lead to pregnancy. If the condom was intact and used correctly, the risk of pregnancy is significantly reduced.

2. Timing of Intercourse: Since you are on birth control and have been consistent with it for three months, your body should be well-adjusted to the hormones, and the likelihood of ovulation is minimal. This means that even if some sperm were to come into contact with the vaginal area, the chances of them leading to pregnancy are low.

3. Sperm Viability: Sperm can live inside the female reproductive tract for up to five days, but they require a conducive environment to survive. If the condom was intact and there was no direct ejaculation into the vagina, the risk of pregnancy remains low.

4. Emergency Contraception: If you are still concerned about the possibility of pregnancy, you might consider taking emergency contraception (Plan B) within 72 hours of the incident. However, given that you are on birth control and the condom was intact, this may not be necessary.

In summary, based on the information provided, your risk of becoming pregnant is quite low. The combination of consistent birth control use and the proper use of a condom significantly reduces the chances of pregnancy. However, if you continue to have concerns or experience any unusual symptoms, it is always a good idea to consult with your healthcare provider for personalized advice and possibly a pregnancy test for peace of mind.

Lastly, remember that while birth control methods are highly effective, no method is 100% foolproof. Regular check-ins with your healthcare provider about your birth control method and any concerns you have can help ensure that you are using the most effective strategy for your needs.
