I forgot to take the first birth control pill on the fifth day of my menstrual period?
Hello Doctor, I have been taking the contraceptive pill Alesse 21 for 3 years.
My last menstrual period was from March 29 to April 4.
I was supposed to start a new pack on April 2, but I forgot to take it.
I took two pills on the evening of April 3 at 9:30 PM (including the pill for April 3).
I will have unprotected intercourse on April 7.
Will this affect the contraceptive effectiveness? Should I take additional contraceptive measures (like condoms)? I'm a bit worried because there was a 7-day break after the previous pack.
Thank you for your patient response!

Hello, when you forget to take your medication, you should take it as soon as you remember, and continue taking the next contraceptive pill at the usual time.
If you miss taking an effective pill for more than 12 hours, in addition to taking the missed pill, it is advisable to use an additional barrier method of contraception for the next seven days.
If you miss a pill and do not experience the expected withdrawal bleeding during the subsequent pill-free interval, you should consider the possibility of pregnancy.
Thank you! Wishing you peace and health, Dr.
Zhang.

When it comes to missed birth control pills, especially in the context of a regimen like the one you are using (the 21-day pill pack), it’s important to understand how to manage missed doses to maintain effective contraception. In your case, you missed a pill on the 5th day of your period, which can raise some concerns about the effectiveness of your birth control.
First, let’s clarify the situation: you have been taking the birth control pill consistently for three years, which is great for maintaining hormonal balance and preventing unintended pregnancies. You mentioned that your last menstrual period was from March 29 to April 4, and you were supposed to start a new pack on April 2. However, you missed the pill on April 2 and took two pills on April 3 instead.
According to the general guidelines for birth control pills, if you miss one pill, you should take it as soon as you remember. If you remember on the same day, taking two pills (the missed one and the one for that day) is acceptable. Since you took the missed pill on April 3, you have effectively mitigated the risk of reduced contraceptive effectiveness for that cycle.
However, there are a few important points to consider:
1. Timing of Unprotected Sex: You mentioned that unprotected sex occurred on April 7. Since you took the missed pill on April 3 and resumed your regular schedule, you should still be protected from pregnancy. The effectiveness of the pill is generally maintained as long as you take it consistently, even if you missed one dose.
2. Additional Contraceptive Measures: While the risk of pregnancy is low, it is always a good practice to use backup contraception (like condoms) for at least 7 days after missing a pill, especially if you have unprotected sex. Since you had unprotected sex shortly after the missed pill, using a backup method would provide additional peace of mind.
3. Monitoring Your Cycle: Keep an eye on your menstrual cycle. If your period is delayed or you experience unusual symptoms, consider taking a pregnancy test. It’s also a good idea to consult with your healthcare provider if you have any concerns or if you miss more pills in the future.
4. Consistency is Key: To maintain the effectiveness of your birth control, try to take your pill at the same time every day. Setting reminders on your phone or using a pill organizer can help you stay on track.
5. Consult Your Healthcare Provider: If you find that you are frequently missing pills or have concerns about your birth control method, it may be worth discussing alternative options with your healthcare provider. There are various forms of contraception available, and finding one that fits your lifestyle can help reduce the chances of missed doses.
In summary, while missing a pill can be concerning, you took the right steps by taking the missed pill as soon as you remembered. Since you resumed taking your pills correctly, you should still be protected from pregnancy. However, using backup contraception for a short period after missing a pill is a prudent approach. Always feel free to reach out to your healthcare provider for personalized advice and support regarding your birth control method.
