Menstrual regulation medication?


The menstrual period was from May 30 to June 3.
Since menstruation started again on June 11, the gynecologist prescribed hemostatic medication and progesterone for three days starting June 12.
After finishing the medication on June 15, menstruation stopped.
When can I expect the next menstrual period? (The usual cycle is about 29 days, and this is the first time experiencing irregularity.)

More Info


Understanding irregular menstrual cycles can be quite challenging, especially when experiencing sudden changes like the ones you've described. Based on your information, it seems that your menstrual cycle has shifted from a regular pattern of approximately 29 days to experiencing an irregular cycle with a very short interval between periods.
Typically, a menstrual cycle is counted from the first day of one period to the first day of the next. In your case, you had your period from May 30 to June 3, and then another one starting on June 11. This indicates a cycle length of only 8 days, which is significantly shorter than your usual cycle. The medications prescribed by your gynecologist, including hemostatic agents and progesterone, are often used to manage heavy bleeding and to help regulate the menstrual cycle.

After taking progesterone, it is common for some women to experience a delay in their next period, as the hormone can influence the timing of ovulation and the subsequent menstrual cycle. Since you finished taking the medication on June 15 and have not had a period since, it is difficult to predict exactly when your next period will occur. Hormonal fluctuations, stress, lifestyle changes, and underlying health conditions can all contribute to irregular cycles.

Here are a few points to consider regarding your situation:
1. Cycle Variability: After experiencing an irregular cycle, it may take some time for your body to return to its normal rhythm. It is not uncommon for cycles to be irregular for a few months after a significant change.

2. Hormonal Influence: The medications you took can affect your hormonal balance. If your body responds well to the treatment, you might expect your next period to return to a more regular pattern. However, if your body is still adjusting, it may take a few cycles to stabilize.

3. Tracking Your Cycle: Keeping a record of your menstrual cycles, including the start and end dates, flow intensity, and any symptoms, can be helpful. This information can provide valuable insights for your healthcare provider if you continue to experience irregularities.

4. Consulting Your Doctor: If your next period does not arrive within a reasonable timeframe (typically within 28-35 days from your last period), or if you experience any concerning symptoms (such as severe pain or excessive bleeding), it is advisable to follow up with your gynecologist. They may recommend further evaluation or tests to rule out any underlying conditions.

5. Lifestyle Factors: Stress, diet, exercise, and sleep can all impact menstrual cycles. Maintaining a healthy lifestyle can help regulate your cycle. Consider incorporating stress-reducing activities, a balanced diet, and regular exercise into your routine.

In conclusion, while it is difficult to predict the exact timing of your next period, it is essential to monitor your body’s responses and maintain open communication with your healthcare provider. If irregularities persist, further evaluation may be necessary to ensure there are no underlying health issues contributing to the changes in your menstrual cycle.
