Oral contraceptives, menstrual issues?


Hello, doctor.
I took my last pill of the contraceptive (Alesse) on November 28, and I got my period on December 3.
I stopped taking the pill in December, and my period still hasn't arrived.
Is this normal? Could it be because my menstrual cycle was irregular to begin with?

Dr. Zhang Kunmin reply Obstetrics and Gynecology


Hello, the questioner: After stopping birth control pills, it is common for the menstrual cycle to be irregular for a while.
However, there are many factors that can affect the menstrual cycle or cause intermenstrual bleeding, such as age, environment, lifestyle, stress, emotional instability, weight changes, medications, emergency contraception, diet, polycystic ovary syndrome, uterine or cervical lesions, infections, ovulation, pregnancy, and breastfeeding, among others.
If you have not been using contraception this month, it is still advisable to take a pregnancy test or consult a gynecologist to check for hormonal imbalances or other causes.
Thank you! Wishing you peace and health, Dr.
Zhang.

More Info


When a woman stops taking birth control pills, it is common to experience irregular periods as the body readjusts to its natural hormonal cycle. Birth control pills, such as the one you mentioned (Alesse), work by providing synthetic hormones that regulate the menstrual cycle. When you stop taking them, your body may take some time to resume its natural hormonal balance, which can lead to changes in your menstrual cycle, including delayed or missed periods.

In your case, you mentioned that you took your last pill on November 28 and had a withdrawal bleed (which is often mistaken for a regular period) starting on December 3. After stopping the pills in December, you have not had a period yet. This situation can be considered normal, especially if you had irregular periods prior to starting the pill. The hormonal changes induced by the pill can mask underlying irregularities in your cycle, and once you stop, those irregularities may resurface.

It is important to note that the time it takes for your menstrual cycle to normalize can vary significantly from one woman to another. Some women may experience a return to regular cycles within a few weeks, while others may take several months. Factors that can influence this include your age, overall health, stress levels, and any underlying medical conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders.

If your periods do not return within a few months, or if you experience other concerning symptoms such as severe pain, excessive bleeding, or signs of pregnancy, it is advisable to consult with a healthcare provider. They may recommend tests to rule out any underlying issues and provide guidance on managing your menstrual health.

In the meantime, maintaining a healthy lifestyle can support your body’s natural hormonal balance. This includes regular exercise, a balanced diet, adequate hydration, and managing stress levels. Tracking your menstrual cycle can also help you and your healthcare provider understand your patterns better and make informed decisions regarding your reproductive health.

In summary, irregular periods after stopping birth control pills can be a normal part of the adjustment process as your body returns to its natural cycle. If you have concerns or if your cycle does not normalize after a reasonable period, seeking medical advice is a prudent step.
