Missed the first day of taking the emergency contraceptive pill?


Hello doctor, my girlfriend has been taking birth control pills regularly for about 2 years.
Recently, due to a busy schedule, she finished her last pack of pills and was supposed to start a new pack 7 days after stopping (on June 22).
However, she mistakenly thought June 23 was the first day to start the new pack and only realized on the evening of June 24 that she missed one pill (the first pill should have been taken on June 22).
I would like to know if taking two pills on the evening of June 24 will affect the contraceptive effectiveness and menstrual regulation.
Thank you!

1.
Emergency contraceptive pills take effect one week after administration.
2.
Taking them one day apart will not affect the menstrual cycle.

When it comes to missing the first day of birth control pills, it's important to understand how hormonal contraceptives work and the implications of missing doses. Birth control pills are designed to regulate hormones in the body to prevent ovulation, and consistent use is crucial for maintaining their effectiveness.

In your situation, your girlfriend has been taking birth control pills regularly for about two years, which is a good foundation for maintaining contraceptive effectiveness. However, the missed dose can create some uncertainty regarding her protection against pregnancy and her menstrual cycle regulation.

1. Taking the Missed Pill: Since your girlfriend realized the mistake on June 24 and took the missed pill (the one intended for June 22) that evening, she has effectively corrected her error. The general recommendation for missed pills is to take the missed pill as soon as you remember, even if it means taking two pills in one day. This is particularly true for combination pills, which are the most common type of birth control pill.

2. Effectiveness: By taking the missed pill on June 24, she should still have adequate contraceptive protection, especially since she has been consistent with her pill regimen prior to this incident. However, if she misses more than one pill or if she misses pills during the first week of a new pack, additional contraceptive measures (like using condoms) may be recommended for at least seven days.

3. Menstrual Cycle Regulation: Missing a pill can sometimes lead to irregularities in the menstrual cycle, such as spotting or an early or late period. However, since she has been on the pill for an extended period, her body is likely accustomed to the hormones, and any irregularities may be temporary. If she experiences significant changes in her cycle or if her period is more than a week late, it would be wise to take a pregnancy test to rule out pregnancy.

4. Future Precautions: To avoid similar situations in the future, it might be helpful for her to set reminders on her phone or use a pill organizer. Consistency is key with birth control pills, and establishing a routine can help prevent missed doses.

5. Consulting a Healthcare Provider: If there are any concerns about missed pills, irregular bleeding, or potential pregnancy, it’s always a good idea to consult with a healthcare provider. They can provide personalized advice based on her health history and current situation.

In summary, taking the missed pill on June 24 should help maintain her contraceptive effectiveness, and she should continue taking her pills as scheduled. If she has any concerns about her menstrual cycle or potential pregnancy, she should consider taking a pregnancy test or consulting her healthcare provider for further guidance.
