Contraceptive pills for menstrual regulation?


Hello, doctor.
I will be going snorkeling in Xiao Liuqiu on September 5th and 6th.
My last menstrual period started on August 3rd.
To be able to go into the water, I started taking birth control pills on August 17th to regulate my cycle, but I only took them for two days because I experienced severe headaches and nausea.
Should I continue taking them? If I stop taking them today, will my period come earlier?

Emily, 20~29 year old female. Ask Date: 2015/08/19

Hello: It is recommended that you temporarily stop taking the medication and consult with a gynecologist for a detailed examination and inquiry.

Managing menstrual cycles with birth control pills can be a useful strategy for many women, especially when planning for specific events like vacations or activities such as snorkeling. However, it's important to understand how these medications work and the potential side effects that can arise.

Birth control pills, or oral contraceptives, are designed to regulate hormonal levels in the body, which in turn helps to manage menstrual cycles. They typically contain synthetic versions of the hormones estrogen and progesterone, which prevent ovulation and stabilize the uterine lining. When taken correctly, they can help to predict and control the timing of menstruation.

In your case, you started taking birth control pills on August 17 to delay your period, which was expected to start around early September. However, you mentioned experiencing significant side effects, including headaches and nausea, after only two days of use. These symptoms can be common side effects of birth control pills, particularly when starting a new regimen. If the side effects are severe or intolerable, it is advisable to stop taking the pills and consult with your healthcare provider.

If you decide to stop taking the pills today, it’s important to note that this may not immediately trigger your period. Stopping the pills can lead to a withdrawal bleed, which typically occurs within a few days to a week after discontinuation. However, the timing of your next period can be unpredictable, especially since you have only taken the pills for a short duration. Some women may experience an earlier onset of their period, while others may find that their cycle remains irregular for a while.

It's also worth mentioning that if you are looking to manage your menstrual cycle for a specific event, there are other options available. For instance, some women choose to take a continuous regimen of birth control pills, which can allow them to skip periods altogether. However, this should always be discussed with a healthcare provider to ensure it is appropriate for your individual health needs.

In summary, if you are experiencing significant side effects from the birth control pills, it may be best to stop taking them and consult with your doctor for alternative options. They can provide guidance on how to manage your menstrual cycle effectively and safely, taking into account your upcoming plans and any health concerns you may have. Always prioritize your health and comfort when considering hormonal treatments.
