Regestrone, which contains the generic hormone norethisterone, is indeed sometimes prescribed to help manage certain types of ovarian cysts by regulating your hormone levels. Regarding your periods, yes, it is very common and normal to experience irregular bleeding, spotting, or changes in your cycle while taking this medication. Your body is simply adjusting to the hormonal changes. Please rest assured that this is a typical response, but I highly recommend keeping your doctor updated on your progress to ensure it is working well for you.

It is completely normal to experience a shorter, lighter bleeding episode after taking Regestrone (norethisterone) to induce your cycle. Because this bleeding is a withdrawal response to the medication rather than a natural physiological period, it can often differ in duration and flow from your usual cycle. Since your pregnancy test is negative, this variation is very common and not a cause for concern. Your body is simply adjusting to the hormonal shift. However, if you experience severe pain, unusual discharge, or if your next cycle remains irregular, please consult your doctor for a quick checkup.

Regestrone 5 mg is used to help control prolonged menstrual bleeding, like your 10-day episode. Continue taking it as prescribed, and schedule a follow-up with your doctor to monitor your response. If bleeding persists, becomes heavier, or you experience side effects, your doctor may adjust the treatment or investigate other causes.

After finishing a course of norethisterone (Regestrone), it is very common for withdrawal bleeding to take anywhere from 3 to 10 days to start. Since it has only been four days and your pregnancy tests are negative, this delay is quite normal, especially with your history of irregular cycles. I recommend waiting another three to six days. If your period still has not started by then, please reach out to your doctor. They can easily evaluate your hormone levels and guide your next steps.

Regestrone contains norethisterone, a hormone used to delay your period. When you stop taking it, your hormone levels drop, triggering a withdrawal bleed. Because this medication temporarily alters your uterine lining and hormone balance, it is very normal for this withdrawal bleed to be much lighter, shorter, or present mostly as spotting compared to your usual period. Your body is simply resetting its natural rhythm. However, if you experience severe abdominal pain, suspect pregnancy, or if your next cycle does not return to normal, it is best to consult your doctor for peace of mind.

Since follicles usually rupture when they reach 18 to 24mm, you will likely ovulate within the next 24 to 48 hours. Your previous irregular cycles after taking Regestrone (norethisterone) won't affect this immediate window because the scan shows your body is ready now. To give yourselves the best chance, I recommend having intercourse today, and continuing every other day (or daily) for the next 4 to 5 days (until cycle day 20 or 21). This ensures sperm are waiting when the egg is released.
