Regarding menstrual induction medications?


Hello, I would like to ask about my situation.
On December 21, I went to the clinic for a transvaginal ultrasound and a pregnancy test, both of which showed no signs of pregnancy (it has been a week since then).
Therefore, the doctor prescribed me two days' worth of medication to induce menstruation, along with some medication to suppress side effects.
I took the medication after dinner on December 21, before breakfast and after dinner on December 22, and finally before breakfast on December 23.
Will I likely get my period before next Wednesday? If I experienced diarrhea once during the medication period, would that be considered a side effect?

If you don't come next Wednesday, you will need to see a doctor for further examination.
There are many causes of diarrhea, and only a doctor can determine the exact reason.

More Info


Menstrual induction medications are often prescribed to help regulate the menstrual cycle, especially in cases where there is a delay or absence of menstruation. These medications can include hormonal treatments such as progestins or estrogen, which work by mimicking the natural hormonal changes that occur during a menstrual cycle.
In your case, it seems that your doctor prescribed you medications to induce menstruation after confirming that you are not pregnant. The timing of when you can expect your period to start after taking these medications can vary based on several factors, including the specific medication used, your individual hormonal balance, and how your body responds to the treatment. Generally, many women may expect their period to start within a few days to a week after completing the course of medication, but this is not guaranteed.
Regarding the side effects, it is important to be aware that menstrual induction medications can cause a range of side effects. Common side effects may include:
1. Nausea: Some women may experience feelings of nausea after taking these medications.

2. Headaches: Hormonal changes can lead to headaches or migraines in some individuals.

3. Breast Tenderness: Hormonal fluctuations can cause breast tenderness or swelling.

4. Mood Changes: Some women may experience mood swings or changes in emotional well-being.

5. Gastrointestinal Issues: This can include symptoms like diarrhea, which you mentioned experiencing. Diarrhea can indeed be a side effect of hormonal medications, although it may also be due to other factors such as dietary changes or stress.

If you experience diarrhea after taking the medication, it could be a side effect, but it is essential to monitor the severity and duration of this symptom. If it is mild and resolves quickly, it may not be a cause for concern. However, if you experience severe diarrhea, dehydration, or other concerning symptoms, it is advisable to contact your healthcare provider for further guidance.

In terms of when to expect your period, since you took the medications as directed, you may see your period start within the week following your last dose. However, if your period does not arrive within a reasonable timeframe (usually within a week after completing the medication), it would be wise to follow up with your healthcare provider for further evaluation. They may want to check for other underlying issues that could be affecting your menstrual cycle.

In summary, menstrual induction medications can be effective in regulating your cycle, but individual responses can vary. Side effects like nausea and gastrointestinal disturbances are common, and monitoring your symptoms is crucial. If you have any concerns or if your symptoms worsen, don't hesitate to reach out to your healthcare provider for advice.
