Missed one day of birth control pill?


Hello, I have been taking birth control pills for almost a year, in a pack of 21 pills, and I take them around the same time every day.
I took a pill on the 20th of this month, but I forgot to take it on the evening of the 21st.
I had sexual intercourse on the morning of the 22nd and then immediately took a pill to make up for the missed dose, and I took my regular pill that evening.
Is there a chance I could get pregnant?

What you need is not medical consultation but rather a remedial course in sexual health knowledge.
For such inquiries, it is recommended to refer to the National Health Administration's "Sexual Happiness e-Learning" or the Obstetrics and Gynecology Society's "Adolescent Contraceptive Guidance Consultation" at http://goo.gl/dc6PfW.

Hello, the correct use of contraceptive pills can achieve a 99% effectiveness rate.
If you forget to take a pill, you should take it as soon as you remember, and continue taking the next pill at the usual time.
If you miss a dose of 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 for more than 24 hours, stop taking the current pack of contraceptive pills, refrain from taking them for seven days (including the days you missed), and then continue with the next cycle.
If you miss a pill and do not experience the expected withdrawal bleeding during the placebo period, you should suspect the possibility of pregnancy.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info


Missing a day of birth control pills can understandably cause concern, especially if you've been diligent about taking them consistently. In your case, since you missed a pill on the 21st but took it the following morning, you have taken the right steps to mitigate the risk of unintended pregnancy.

When it comes to combination birth control pills (which contain both estrogen and progestin), the general advice is as follows:
1. Timing of Missed Pill: If you miss a pill and it's less than 24 hours late, you should take the missed pill as soon as you remember. Since you took the missed pill on the morning of the 22nd, you have effectively minimized the risk of ovulation.

2. Sexual Intercourse After Missing a Pill: Engaging in sexual intercourse after missing a pill can increase the risk of pregnancy, especially if you missed a pill during the first week of your pill pack. However, since you took the missed pill the next morning, you are still protected, provided you continue taking your pills as scheduled.

3. Backup Contraception: If you miss a pill and have unprotected sex, it is often recommended to use backup contraception (like condoms) for at least the next seven days, especially if you missed a pill during the first week of your pack. In your case, since you took the missed pill promptly, you may not need to worry as much, but using backup contraception can provide additional peace of mind.

4. Emergency Contraception: If you are still concerned about the possibility of pregnancy, you can consider emergency contraception (like Plan B) if you had unprotected sex. This is most effective when taken within 72 hours after unprotected intercourse, but it can work up to five days after.

5. Consult Your Healthcare Provider: If you have any doubts or if this situation happens frequently, it’s a good idea to consult with your healthcare provider. They can provide personalized advice based on your health history and the specific type of birth control you are using.

6. Future Prevention: To avoid missing pills in the future, consider setting a daily reminder on your phone or using a pill organizer. Some people find it helpful to take their pills at the same time as another daily routine, like brushing their teeth.

In summary, since you took the missed pill the next morning and continued with your regular schedule, your risk of pregnancy is significantly reduced. However, if you have any lingering concerns or experience any unusual symptoms, it’s always best to consult with a healthcare professional for further guidance. Remember, consistent use of birth control is key to its effectiveness, and having a plan in place for missed doses can help you stay on track.
