When did you start taking progesterone?

Patient's question:

Medical Description: Due to irregular menstruation and amenorrhea, I want to have a baby.
Treatment history and effectiveness: The doctor has prescribed medication for an artificial cycle, but I'm not quite clear about how to take progesterone.
Help needed: Could you please tell me on which day to start taking progesterone and for how many days? Thank you

Doctor's answer:

Taking progesterone should not be
Generally, after taking progesterone, your period will come only after stopping the medication. However, taking progesterone intermittently has no effect, and your period might even come within two or three days of stopping the medication. It cannot be made to come according to your wishes.
Take progesterone and stop once your period starts
If you are taking progesterone to induce your period, stop as soon as it starts. This medication is not taken in cycles; once the purpose is achieved, it can be stopped. If you are taking it to extend your menstrual cycle, calculate the timing carefully and do not stop until the goal is reached.
Progesterone should not be overused, as it can cause weight gain
Progesterone is a hormone medication with relatively minor side effects. Occasionally taking it once or twice, or using it occasionally for situations like swimming or exams, is acceptable. However, consistently taking progesterone can lead to weight gain—hormone medications often have this effect. Therefore, it is best not to take it. If you rely on progesterone every time and experience periods only when taking it, it is essential to seek medical treatment.
