Emergency contraceptive pill
Hello, doctor.
I would like to ask about my third pack of pre-exposure prophylaxis (PrEP) this month.
I started taking it on April 5, but I forgot to take the second pill on April 6.
I remembered on April 7 and took two pills.
I had unprotected intercourse early this morning, but I continued to take my PrEP at the usual time on April 8.
Do I still need to take emergency contraception, or can I just continue with my regular PrEP schedule?

1.
For pregnancy concerns, please take a home pregnancy test or visit a gynecologist for examination and evaluation four weeks after your most recent sexual intercourse.
2.
Birth control pills must be taken continuously for at least 7 days to ensure contraceptive effectiveness.

More Info
When it comes to missing a birth control pill, it's important to understand the specific circumstances and the type of contraceptive you are using. In your case, you mentioned that you missed the second pill of the first week of your new pack but took two pills the following day to catch up. You also had unprotected intercourse after missing the pill.
Generally, if you miss a pill, the recommendation is to take it as soon as you remember. If you remember on the same day, you can simply take the missed pill and continue with your regular schedule. Since you took two pills the next day, you effectively caught up, which is a good step.
However, since you had unprotected intercourse after missing a pill, there is a potential risk of pregnancy. The effectiveness of birth control pills can decrease if pills are missed, especially during the first week of a new pack. The first week is critical because it is when your body is still adjusting to the hormones, and ovulation can occur if the hormone levels drop.
In your situation, since you had unprotected intercourse after missing a pill, it is advisable to consider emergency contraception (EC) if you are concerned about the risk of pregnancy. Emergency contraception is most effective when taken as soon as possible after unprotected intercourse, ideally within 72 hours, but some forms can be effective up to 5 days after.
You should also continue taking your regular birth control pills as scheduled. If you are unsure about the need for emergency contraception or have further questions about your birth control method, it is best to consult with a healthcare provider. They can provide personalized advice based on your health history and specific situation.
In summary, while you have taken steps to mitigate the missed pill by taking two the next day, the risk of pregnancy still exists due to the timing of unprotected intercourse. Therefore, considering emergency contraception is a prudent option if you are concerned. Always remember to keep track of your pill schedule and consult with your healthcare provider for any uncertainties regarding your contraceptive method.
