Typically, a period should start within 3 to 10 days after finishing Regestrone (norethisterone). Since it has been 73 days, I highly recommend booking an appointment with your gynecologist now rather than waiting. There are many common, manageable reasons for this delay, such as hormonal fluctuations, stress, or thyroid imbalances, and your doctor can run simple tests to find the exact cause. In the meantime, if you are sexually active, taking a home pregnancy test is a helpful first step. Your doctor will guide you gently on the best way to safely regulate your cycle.

Yes, you can use Regestrone (norethisterone) to safely delay your period for your upcoming event. Since your period is expected on March 17, you should start taking the tablets three days before, on March 14. The typical dosage is one 5 mg tablet taken three times a day. You can continue taking them for the duration of the event, but it is generally recommended not to use them for more than 10 to 14 days. Your period should return 2 to 3 days after stopping the medication. I wish you a wonderful time at your family event, and please consult your doctor to ensure this is suitable for you.

After finishing a 21-day course of Regestrone (norethisterone) on December 14th, a withdrawal bleed typically starts within 3 to 10 days. Sometimes, your body just needs a little extra time to reset its hormone levels, or mild stress can cause a delay. If you are sexually active, taking a home pregnancy test is a safe first step. If your period still hasn't arrived after 10 to 14 days from stopping the medicine, please consult your gynecologist. They can gently evaluate your hormone levels to ensure everything is on track.

It is very common to experience cycle delays after using hormonal medications. Your risk of pregnancy is very low because you used protection and took emergency contraception (levonorgestrel). Both norethisterone and levonorgestrel introduce significant hormone changes, which easily cause irregular bleeding and delay your subsequent period. While a higher BMI can sometimes slightly reduce the efficacy of levonorgestrel, your use of barrier protection provides excellent reassurance. Your body is simply resetting its natural rhythm. To help ease your mind, taking a simple home pregnancy test can provide definitive reassurance. Please reach out to a doctor if your period is delayed by more than two weeks.

Transitioning from Regestrone (norethisterone) to Dronis 30 (ethinyl estradiol/drospirenone) often causes temporary breakthrough bleeding as your body adapts to the new hormone levels. Trapin MF (tranexamic acid/mefenamic acid) helped control the initial flow, but this new spotting is a common adjustment response. Your 4cm ovarian cyst is likely being managed by the Dronis 30, which helps regulate ovarian activity. Please continue taking your Dronis 30 as scheduled. I highly recommend contacting your gynecologist so they can evaluate this bleeding pattern and monitor your cyst with a follow-up ultrasound to ensure everything is resolving safely.

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.
