First Time Taking Birth Control Pills: Is It Normal to Miss Your Period?

I took the emergency contraceptive pill for the first time, and my menstrual cycle has not started yet?

Hello, I am taking the contraceptive pill for the first time, specifically Qlaira with 21 pills.
I started taking it on the first day of my menstrual cycle.
I am currently on the tenth day of taking it, but my period hasn't stopped yet.
Is this normal?

If bleeding lasts more than a week, consider taking the next dose of the contraceptive pill on days 3 to 5 of the next menstrual cycle, or consult a physician about switching to a different contraceptive method.

More Info

When it comes to starting birth control pills, particularly the combination oral contraceptive pills like "Chirian" (which I assume is a brand name for a combined oral contraceptive), it's important to understand how these medications work and what to expect during the initial cycle of use.

Firstly, it is not uncommon for women to experience changes in their menstrual cycle when they first start taking birth control pills. The primary purpose of these pills is to regulate hormones in the body to prevent ovulation, and this hormonal adjustment can lead to variations in menstrual bleeding patterns. Some women may experience lighter periods, while others may notice that their periods are delayed or even missed altogether during the first few months of taking the pill.

In your case, since you mentioned that you have taken the pills for ten days and have not yet seen your period, this can be considered a normal response. The birth control pills work by providing a steady level of hormones, which can sometimes suppress the natural menstrual cycle temporarily. If you started taking the pills on the first day of your menstrual cycle (the first day of bleeding), it is expected that you may not have a withdrawal bleed (the period-like bleeding that occurs during the placebo week) until you complete the active pills and enter the placebo phase.

However, it's essential to keep in mind that while some women may not experience a period during the first month of taking the pill, others may still have a withdrawal bleed. If you do not have a withdrawal bleed after completing the active pills, it is advisable to take a pregnancy test to rule out pregnancy, especially if you have had unprotected intercourse during the time you were on the pill.

Additionally, if you have any concerns about missed periods or other side effects, it is always a good idea to consult with your healthcare provider. They can provide personalized advice based on your medical history and any other medications you may be taking. They can also help you understand what to expect in the following months as your body adjusts to the hormonal changes from the birth control pills.

In summary, missing your period while on birth control pills, especially during the first cycle, can be normal due to the hormonal adjustments your body is undergoing. However, if you continue to miss periods or have any other concerning symptoms, do not hesitate to reach out to your healthcare provider for further evaluation and guidance.
