Regestrone contains a hormone called norethisterone, which acts like progesterone. Normally, a period is triggered when your body's progesterone levels suddenly drop. When you take this medication, it maintains high hormone levels, which can delay a period. However, when you finish your short prescribed course and stop taking it, your hormone levels suddenly drop. This rapid decline mimics your natural cycle, signaling your body to shed the uterine lining and start your period. It is a very safe and common way to help reset your cycle. Please follow your doctor's instructions on when to stop the medication.

You can have sex while taking Regestrone 5 mg, but it does not prevent pregnancy, so use contraception if needed. It is best to avoid alcohol, as it can affect your liver and may interfere with how the medication works.

Regestrone (norethisterone) is used to delay your period, but it is not a reliable contraceptive. Because you had unprotected sex, there is a risk of pregnancy. Your period should typically start within 3 to 7 days after you stop taking the medication. If your period does not arrive within a week of stopping it, or if you feel anxious, I gently recommend taking a home pregnancy test or speaking with your doctor for guidance and peace of mind.

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.

This is a very common and manageable issue. Spotting around day 15 of your cycle is often related to temporary hormonal fluctuations during ovulation. Since it persisted despite taking Regestrone (norethisterone), other possibilities include benign conditions like uterine polyps, small fibroids, or minor hormonal imbalances. I gently recommend consulting your gynecologist. They can perform a routine pelvic ultrasound or simple hormone tests to pinpoint the exact cause and tailor a safe treatment plan to help you feel comfortable and secure.

After finishing a three-month course of Regestrone (norethisterone), your body is adjusting to shifting hormone levels, which can temporarily cause heavy bleeding and cramping. Additionally, your hypothyroidism can influence your menstrual cycle if thyroid levels aren't fully balanced. The watery discharge might simply be related to these hormonal changes or a mild, easily treatable irritation. Since these symptoms are persistent, I highly recommend gently reaching out to your gynecologist.
