Delayed Period After Taking Menstrual Induction Pills: What to Expect - Obstetrics and Gynecology

The eighth day after taking the menstrual induction medication, menstruation has still not occurred?


I got my period on September 2nd, and I had sexual intercourse on October 13th, using a condom the entire time.
On October 14th, my period still hadn't arrived, so I went to see a doctor.
An ultrasound was performed, and it showed that I was not pregnant.
The doctor prescribed me medication to induce my period, which I took four times a day for three days.
In the past, my period would usually start by the sixth day, but this time it's been eight days and it still hasn't come, even though I feel like it should.
I wake up with abdominal bloating and pain.
Additionally, my gynecologist mentioned that my menstrual cycle is irregular and advised me to take "menstrual regulation medication." He said to take it for five consecutive days, and my period should be regular next month.
I have previously taken "ovulation medication" for 21 days, which caused weight gain, so I'm hesitant to take the menstrual regulation medication and only feel comfortable taking the medication to induce my period.
Is there a chance that this magical five-day menstrual regulation medication could also cause weight gain?

Dr. Huang Yiwen reply Obstetrics and Gynecology


Hello Ms.
Yin: Generally speaking, after taking menstrual induction medication, you can expect your period to arrive within about seven to ten days.
If your period has not started after ten days, it would be advisable to take a pregnancy test to rule out pregnancy.
The five consecutive days of menstrual regulation medication mentioned by the doctor likely refers to ovulation induction medication.
Some individuals may experience weight gain while taking ovulation medication, but this is not very common.
You can try it out and see how it goes.

More Info


When it comes to delayed menstruation after taking menstrual induction pills, there are several factors to consider. First, it’s important to understand how these medications work. Menstrual induction pills, often containing hormones such as progesterone or estrogen, are designed to help regulate the menstrual cycle and can prompt the onset of menstruation. However, the response to these medications can vary significantly from person to person.

In your case, you mentioned that you took the induction pills and are now experiencing a delay in your period, even after the expected time frame. It’s not uncommon for menstrual induction pills to take some time to work, and factors such as stress, hormonal imbalances, and individual body responses can all play a role in how quickly your period arrives. The fact that you have experienced bloating and abdominal discomfort may indicate that your body is responding to the hormonal changes, but it does not guarantee that your period will start immediately.

Typically, if you have taken the medication as prescribed and have not experienced any adverse effects, you should allow some time for your body to respond. It’s also worth noting that some women may experience a delay in their period even after taking these medications, which can be frustrating. If your period does not arrive within a week or so after completing the course of the medication, it would be advisable to follow up with your healthcare provider for further evaluation.

Regarding the "调经药" (regulating medication) that your gynecologist prescribed, it’s important to discuss any concerns you have about potential side effects, including weight gain. Many hormonal medications can have varying effects on weight, and individual responses can differ. While some women may experience weight gain due to hormonal changes, others may not notice any significant changes. It’s crucial to communicate your concerns with your doctor, who can provide you with more tailored advice based on your medical history and current health status.

In summary, delayed menstruation after taking menstrual induction pills can be influenced by various factors, and it’s essential to give your body some time to respond. If your period does not arrive soon, or if you have any concerning symptoms, don’t hesitate to reach out to your healthcare provider for further guidance. Additionally, when considering any new medications, including those for regulating your menstrual cycle, it’s always best to discuss potential side effects and your specific concerns with your doctor to ensure you are making informed decisions about your health.
