What Happens If You Skip a Pill in Your Birth Control Pack?

What happens if you skip a dose of the emergency contraceptive pill?

I took a 28-day contraceptive pill and today I finished the 28th pill.
I realized that I skipped the 6th pill, and the first six pills seemed to be sedatives, which means I was taking a different medication that day.
What impact could this have? Should I stop and wait for my next period to start a new pack, or can I continue with the next pack?

When it comes to birth control pills, consistency is key to maintaining their effectiveness. If you skip a pill in your birth control pack, the impact on your contraceptive protection can vary depending on the type of pill you are taking (combination or progestin-only) and when you missed the pill in relation to your cycle.

In your case, you mentioned that you are taking a 28-day birth control pack and that you skipped the 6th pill, which you noted is a placebo or inactive pill. Typically, in a 28-day pack, the first 21 pills are active (containing hormones), and the last 7 pills are inactive. If you missed an active pill, it could potentially reduce the effectiveness of the birth control, especially if you missed it during the first week of starting a new pack. However, since you skipped an inactive pill, it generally does not affect your contraceptive protection. The purpose of the inactive pills is to allow for a withdrawal bleed, similar to a menstrual period, and skipping them does not compromise the effectiveness of the active pills taken earlier in the cycle.

Here’s what you should consider:
1. Continue Taking Active Pills: Since you have completed the 28-day pack, you can continue to the next pack without any interruption. There is no need to stop or wait for your next period to start a new pack.

2. Monitor for Side Effects: If you are taking a different medication (like a sedative) that may interact with your birth control, it’s important to consult with your healthcare provider. Some medications can reduce the effectiveness of hormonal contraceptives, leading to a higher risk of unintended pregnancy.

3. Use Backup Contraception: If you are concerned about the effectiveness of your birth control due to the missed pill or any interactions with other medications, consider using a backup method of contraception (like condoms) until you are sure that your birth control is effective again.

4. Consult Your Healthcare Provider: If you have any doubts or experience any unusual symptoms, it’s always a good idea to reach out to your healthcare provider. They can provide personalized advice based on your medical history and current medications.

5. Regular Check-ups: Regular follow-ups with your healthcare provider are essential to ensure that your birth control method is still the best option for you and to discuss any side effects or concerns you may have.

In summary, skipping an inactive pill typically does not affect your birth control's effectiveness. You can continue with your next pack as scheduled. However, if you have taken another medication that may interact with your birth control, or if you have any concerns about your contraceptive method, it’s best to consult with your healthcare provider for tailored advice.
