Early menstruation


Hello, doctor.
I started taking menstrual regulation medication in May and stopped after six months in November.
During this period, my menstrual cycle was normal, maintaining a 28-day cycle.
My menstrual period started on November 11, and then I had another one on November 24.
The flow on the first day was slightly lighter than usual, requiring the use of a sanitary pad, but by the second and third days, there was almost no flow.
Can you tell me if the period on November 24 counts as a menstrual period? Is this related to stopping the medication since it was my first menstrual cycle after discontinuation? Should I go to the hospital for an examination? How should I calculate my next menstrual period? Thank you.

Hello, Xiaowen.
Your menstrual period occurred on November 11 and November 24, with only a 13-day interval, which is not considered a normal cycle and is classified as abnormal bleeding.
The most likely cause is hormonal imbalance leading to irregular menstruation.
Since you have been using medication to regulate your menstrual cycle for the past six months and suddenly stopped this month, your body and the hormones related to ovarian function may not have adjusted in time, resulting in hormonal disruption and irregular periods.
If the bleeding is not excessive, does not last too long, and eventually stops on its own, you can temporarily monitor the situation and wait for your next period to see if it gradually returns to normal.
However, if the bleeding is heavy, lasts too long, or if you experience significant abdominal discomfort, it may indicate a problem, and you should seek medical attention.
Sincerely, Dr.
Lu Licheng, Department of Obstetrics and Gynecology, Taoyuan Hospital.

More Info


Understanding early menstruation after stopping birth control can be a complex issue, as it involves various physiological changes that occur in the body once hormonal contraceptives are discontinued. When you stop taking birth control pills, your body begins to readjust to its natural hormonal cycle, which can lead to irregularities in your menstrual cycle for a period of time.

In your case, you mentioned that you had a regular menstrual cycle while on the medication, with a 28-day cycle. After stopping the birth control in November, you experienced your first period on November 11, followed by another bleeding episode on November 24. The first day of your second bleeding episode was lighter than usual, and by the second and third days, the flow was almost negligible.

To address your questions:
1. Is the November 24 bleeding considered a menstrual period?
Yes, the bleeding you experienced on November 24 can be considered a menstrual period, especially since it occurred shortly after your first period post-birth control. However, the lightness of the flow may indicate that your body is still adjusting to the hormonal changes after stopping the pill. It is not uncommon for the first few cycles after discontinuation to be lighter, shorter, or even irregular.

2. Is this early menstruation due to stopping the birth control?
Yes, the early onset of menstruation can be attributed to the cessation of the birth control pills. When you stop taking hormonal contraceptives, your body may take some time to recalibrate its natural hormonal levels, which can lead to variations in the menstrual cycle. Some women may experience shorter cycles, while others may have longer cycles or missed periods altogether during this adjustment phase.

3. Should you see a doctor?
If you continue to experience irregularities in your menstrual cycle, such as very light periods, prolonged bleeding, or if you have any other concerning symptoms (like severe pain or unusual discharge), it would be wise to consult with a healthcare provider. They can perform a thorough evaluation to rule out any underlying conditions and provide guidance on what to expect as your body readjusts.

4. How to calculate your next menstrual period?
After stopping birth control, it may take a few cycles for your body to establish a regular pattern again. You can start counting your next menstrual cycle from the first day of your last period (November 24). If your cycles return to a regular pattern, you can expect your next period to occur approximately 28 days later, around December 22. However, keep in mind that cycles may vary in length as your body readjusts.

In summary, experiencing an early period after stopping birth control is not uncommon, and it is often a sign that your body is beginning to return to its natural hormonal rhythm. Monitoring your cycles for the next few months will help you understand your body’s adjustments better. If you have any concerns or if your cycles do not stabilize, seeking medical advice is always a good step to ensure your reproductive health is on track.
