Emergency contraceptive pill


Hello, doctor.
Last month, I took the emergency contraceptive pill as scheduled.
During the break period, I experienced light bleeding for a few days, and I'm unsure when to consider it as the start of my menstrual period.
Can I start taking the contraceptive pill on the sixth day after the bleeding begins this month? Thank you, doctor.

Yes, you can start taking birth control pills on day six of your period, but there are some important considerations to keep in mind. Birth control pills are designed to prevent ovulation and regulate menstrual cycles, and the timing of when you start taking them can affect their effectiveness and your menstrual cycle.

Typically, the first day of your period is considered day one. If you start taking the pill within the first five days of your period, it is effective immediately in preventing pregnancy. However, starting on day six means that you may not have the immediate contraceptive effect, and you should use an additional form of contraception, such as condoms, for the first seven days of taking the pill.

It's also important to note that if you have irregular periods or are unsure about when your period starts, it might be beneficial to consult with a healthcare provider. They can help you determine the best time to start the pill based on your individual circumstances. Additionally, if you have any concerns about the amount of bleeding or any other symptoms, it's advisable to seek medical advice.

When starting birth control pills, it's crucial to follow the instructions provided by your healthcare provider or the information that comes with the medication. Consistency is key; taking the pill at the same time every day can help maintain its effectiveness. If you miss a dose, follow the guidelines on what to do next, as missing pills can increase the risk of unintended pregnancy.

Moreover, if you have recently stopped taking other hormonal contraceptives, such as the pill or an IUD, your body may take some time to adjust. This adjustment period can sometimes lead to irregular bleeding patterns, which can make it challenging to determine the start of your cycle.

In summary, starting birth control pills on day six of your period is possible, but you should be aware of the need for additional contraception during the first week. Always consult with your healthcare provider for personalized advice, especially if you have any concerns about your menstrual cycle or contraceptive options. They can provide guidance tailored to your health needs and help you make informed decisions about your reproductive health.
