Pregnancy Risks with Birth Control Pills: Your Questions Answered - Obstetrics and Gynecology

When it comes to understanding the risks of pregnancy while on birth control pills, it's essential to consider several factors, including the timing of pill intake, the type of birth control used, and the timing of unprotected intercourse.
In your case, you mentioned that you started taking a 28-day birth control pill pack on the second day of your menstrual period. Generally, if you start taking combination birth control pills (which contain both estrogen and progestin) during the first five days of your menstrual cycle, you are protected from pregnancy immediately. However, if you start taking the pill after this window, it typically takes about seven days for the pills to become fully effective. Since you began on the second day of your period, you should have been protected from the start, assuming you continue to take the pills consistently and correctly.

Regarding the unprotected intercourse that occurred on the sixth and seventh days after starting the pill, the risk of pregnancy is relatively low, especially since you were already taking the pill for a sufficient duration to ensure its effectiveness. The fact that there was no ejaculation (internal ejaculation) further reduces the risk of pregnancy, as pre-ejaculate fluid can contain sperm, but the likelihood of conception from this is significantly lower than from full ejaculation.

As for whether you can continue to have unprotected intercourse this month, the answer is yes, as long as you continue to take your birth control pills as directed. Consistency is key with oral contraceptives; missing doses or taking them at irregular times can increase the risk of pregnancy. If you take your pills at the same time every day, your protection against pregnancy remains effective.

It's also worth noting that while birth control pills are highly effective when taken correctly, no contraceptive method is 100% foolproof. If you ever have concerns about potential pregnancy or if you miss a pill, it's advisable to consult with your healthcare provider. They may recommend using a backup method, such as condoms, especially during the first month of starting a new pill regimen or if you have missed any doses.

In summary, based on the information provided, the likelihood of pregnancy from the described scenario is low, and you can continue to have unprotected intercourse as long as you maintain your pill regimen. However, always stay informed about your birth control method and consult with your healthcare provider for personalized advice and to address any concerns you may have.
