After finishing a course of Regestrone (norethisterone), it typically takes about 3 to 10 days for your withdrawal bleed to begin, so two days is still very early. Your lower belly and leg cramps are very common signs that your body is responding to the hormonal shift and preparing to start your period. Since your pregnancy tests are negative, you can feel reassured. Try to rest, stay hydrated, and give your body a few more days. If your period doesn't start within a week, or if the cramps become severe, please consult your healthcare provider.

After finishing Regestrone (norethisterone), it typically takes 3 to 10 days for withdrawal bleeding to begin, though it can sometimes take up to 14 days. Because you have PCOS, underlying hormonal imbalances can occasionally delay this response. Since you have confirmed you are not pregnant, please be reassured that this delay is common and not a cause for alarm. I suggest waiting another 5 days. If your period still hasn't started after a full two weeks post-treatment, please consult your gynecologist to discuss the next steps.

Even though you are successfully releasing eggs, your doctor likely prescribed Regestrone (norethisterone) to support the next crucial step of your fertility journey. Regestrone is a progesterone-like hormone. While your body naturally produces and releases eggs, it also needs the right hormonal balance to prepare and stabilize the lining of your womb. This ensures a welcoming environment for a fertilized egg to safely implant and grow. Think of it as preparing the soil now that the seed is ready.

It is very common to feel anxious when waiting for a cycle to return. After completing the course of Regestrone (norethisterone), your friend can generally expect her period to start within 3 to 10 days after taking the very last pill. Since her pregnancy test is negative, she can take a deep breath and rest assured. Her body is likely just adjusting after her medical abortion in April, and her daily thyroid medication is perfectly safe to continue. If her period does not arrive within 10 days of finishing the medication, she should gently consult her gynecologist for further guidance.

Regestrone (norethisterone) can safely delay your period, but using it with recent irregular bleeding requires care. Since your cycle is already fluctuating, norethisterone might cause some spotting, bloating, or mild headaches. It is generally safe for short-term use, but delaying your period for an extended duration is not typically recommended without a doctor's supervision, as it can further disrupt your natural cycle. After stopping the medication, your period should return within 3 to 7 days. I gently recommend speaking with your doctor to rule out any underlying causes for your irregular bleeding before starting.

In PCOS, a hormonal imbalance often means your body doesn't produce enough progesterone to regulate your cycle. This causes the uterine lining to build up and shed irregularly. Medications like Sysron N and Regestrone contain norethisterone, a synthetic progesterone. This hormone steps in to stabilize your uterine lining, mimicking your body's natural signals to control and stop the bleeding. It is very common to need this support.
