Issues with the use of menstrual induction medications?


Hello, doctor.
A few days ago, I visited a gynecologist and started taking medication to induce my period.
The doctor instructed me to take the medication from the 14th to the 21st, with my period expected to start between the 21st and 30th.
During the medication period, the doctor mentioned that a small number of people might experience light bleeding.
However, I started having light bleeding on the 16th, and by the 17th, the bleeding increased significantly.
I'm unsure if this means my period has already started.
Can I continue taking the medication?

More Info


When it comes to menstrual induction medications, it's essential to understand their purpose, how they work, and the appropriate course of action if you experience unexpected bleeding. Menstrual induction medications are typically prescribed to help regulate or induce menstruation in individuals who may have irregular cycles or are experiencing amenorrhea (the absence of menstruation). These medications can include hormonal treatments such as progestins or estrogen, which work by mimicking the natural hormonal fluctuations that occur in a typical menstrual cycle.

In your case, you started taking the medication on the 14th and were advised to continue until the 21st. The expectation was that your menstrual period would commence between the 21st and 30th. However, you began experiencing light bleeding on the 16th, which then increased on the 17th. This situation raises a few important considerations.

Firstly, the bleeding you are experiencing could indeed be a sign that your menstrual period has started. It is not uncommon for individuals taking menstrual induction medications to experience breakthrough bleeding or spotting before their expected period. This can happen as the body responds to the hormonal changes induced by the medication. If the bleeding is heavier and resembles a typical menstrual flow, it is likely that your period has begun.

Regarding whether to continue taking the medication, it is generally advisable to stop taking menstrual induction medications once your period has started. Continuing the medication during menstruation can lead to excessive bleeding or other complications. However, if you are unsure whether the bleeding is indeed your menstrual period or if you have concerns about the amount of bleeding, it is crucial to consult your healthcare provider for personalized advice.

In addition to the potential for breakthrough bleeding, some individuals may experience side effects from menstrual induction medications, such as nausea, breast tenderness, or mood changes. If you encounter any severe side effects or if the bleeding becomes excessively heavy (soaking through a pad or tampon every hour for several hours), you should seek medical attention promptly.

In summary, based on your description, it seems likely that your menstrual period has started. It is advisable to stop taking the menstrual induction medication and monitor your bleeding. If you have any doubts or if the bleeding is unusually heavy or accompanied by severe pain, please reach out to your healthcare provider for further guidance. They can provide you with the best advice tailored to your specific situation and ensure that you remain healthy and safe during this time.
