Managing Birth Control: What to Do After Stopping Mid-Pack - Obstetrics and Gynecology

Taking birth control pills halfway through?


Hello Dr.
Lu: Last month I switched to taking Diane, and the side effects were very uncomfortable.
I stopped taking it this Monday (August 31) and have about a week’s worth of pills left.
However, my period still hasn’t arrived as of today.
Should I wait until the fifth day of my period to start taking it again, or should I wait until the following Monday after a seven-day break to start a new pack?

Dr. Lü Lizheng reply Obstetrics and Gynecology


Your period should be coming soon.
It is recommended to wait a few more days to see.
After your period starts, take the next month's birth control pill on the fifth day.

When it comes to managing birth control, particularly after stopping a hormonal contraceptive mid-pack, there are several important considerations to keep in mind. First, it’s essential to understand how hormonal birth control works and the implications of discontinuing it before completing a pack.

When you stop taking a birth control pill like Dianne (or any combination oral contraceptive), your body begins to adjust back to its natural hormonal cycle. This adjustment can lead to a delay in the onset of your menstrual period, which is what you are currently experiencing. It is not uncommon for women to have irregular bleeding or a delayed period after stopping hormonal contraceptives, especially if they have not completed the pack.

In your case, since you stopped taking the pill after approximately three weeks, you may not experience a withdrawal bleed (the period that occurs after stopping the pill) immediately. It can take some time for your body to regulate itself, and it’s possible that your period may not arrive until several days or even weeks after stopping the medication.
Regarding your question about when to start a new pack of pills, the general recommendation is to wait until your menstrual cycle has returned to a regular pattern. If you have not had a period by the time you would normally start a new pack, you have a couple of options:
1. Wait for Your Period: You can wait for your period to arrive. If it does come, you can start taking the new pack on the first day of your period, which is the standard practice for starting a new cycle of birth control pills.

2. Start the New Pack: If you do not have your period by the time you would normally start a new pack (which would be about a week after stopping), you can choose to start the new pack anyway. However, it’s important to note that if you start the new pack without having a period, you may not have immediate contraceptive protection. It’s advisable to use a backup method of contraception, such as condoms, for at least the first seven days of taking the new pack.

3. Consult Your Healthcare Provider: Since you experienced significant discomfort with the previous pill, it may be beneficial to consult with your healthcare provider about your symptoms and the best course of action moving forward. They can provide personalized advice based on your health history and current situation.

In summary, after stopping a hormonal contraceptive mid-pack, it’s common to experience a delay in your menstrual cycle. You can either wait for your period to start the new pack or begin the new pack without a period, keeping in mind the need for backup contraception. Always consult with your healthcare provider for tailored advice and to address any concerns regarding side effects or the transition between different contraceptive methods.
