Regarding contraceptive pills?


Hello, doctor: I would like to ask if taking birth control pills on the sixth day after the onset of menstruation still provides contraceptive protection.
Additionally, does long-term use of birth control pills affect the likelihood of conceiving in the future?

Jan, 20~29 year old female. Ask Date: 2001/08/10

Dr. Li Guanghan reply Obstetrics and Gynecology


Taking it on the sixth day also has contraceptive effects.
Long-term use of exogenous hormones can interfere with the body's hormones and may affect the fertility rate immediately after discontinuation, but normal fertility rates can be restored after a few months.

When it comes to understanding birth control pills, timing and future fertility concerns are essential topics for many women. Let's address your questions regarding the effectiveness of birth control pills when taken at specific times and their long-term impact on fertility.

First, regarding the timing of starting birth control pills, if you begin taking the pill on the sixth day of your menstrual cycle, it can still be effective, but the level of effectiveness depends on the type of pill you are using and when you start. Most healthcare providers recommend starting the pill at least seven days before engaging in unprotected intercourse to ensure maximum effectiveness. If you start taking the pill during your period, it is generally effective immediately, but starting it later in your cycle may require additional contraceptive methods (like condoms) for the first seven days. It's crucial to follow the instructions provided by your healthcare provider or the information leaflet that comes with your medication.

Now, concerning the long-term effects of taking birth control pills on future fertility, research indicates that long-term use of hormonal contraceptives does not significantly affect a woman's ability to conceive after discontinuation. Most women will return to their normal fertility levels shortly after stopping the pill. Studies have shown that while some women may experience a temporary delay in returning to their baseline fertility, this is usually not a long-term issue. In fact, many women find that their menstrual cycles become more regular after stopping the pill, especially if they had irregular cycles before starting it.

It's also important to note that birth control pills work by regulating hormones to prevent ovulation, and they can also help manage other menstrual-related issues, such as heavy bleeding or painful periods. However, if you have concerns about your fertility or the impact of hormonal contraceptives on your reproductive health, it's advisable to have a discussion with your healthcare provider. They can provide personalized advice based on your medical history and current health status.

In summary, starting birth control pills on the sixth day of your cycle can still provide contraceptive protection, but it may require additional precautions initially. Long-term use of birth control pills is not associated with a decreased likelihood of future pregnancies, and most women can expect to regain their fertility soon after stopping the medication. If you have specific concerns or underlying health issues, consulting with a healthcare professional is always the best course of action. They can help you navigate your options and ensure that you make informed decisions regarding your reproductive health.

Please choose a lower dose contraceptive pill. A triphasic pill is preferable, and it is best to take it for six months followed by a one-month break (to reduce excessive suppression of ovulation during the medication break).
