Patient's Query

Hi doctor,

I have a 3-year-old child. Now I want to avoid unplanned pregnancy. Usually, mine is a 27-day cycle. I got my last period 35 days ago. Till now, I have not got the period. I have not done any pregnancy tests. I started taking Regestrone tablets from last week for two days (morning and night, one pill each) still, my periods did not start. But I am having period pain. What to do? Please help.

Hi,

Welcome to icliniq.com.

I understand your concern. Firstly, Regestrone (Norethisterone) has to be taken for five days twice or thrice daily. A lesser dose may not help to induce your period. The lesser dose may be the cause of your delayed period. Secondly, even after completion of dosage, it takes about 7 to 10 days to start. Thirdly as you have not taken a pregnancy test, I would suggest you kindly do that. If it is negative kindly revert. Also, kindly revert to the contraceptive option. Regards.

Patient's Query

Hi doctor,

Thanks for the reply.

Just now, I tested with the pregnancy test kit, and it shows negative only. I have a doubt. I took two Regestrone tablets. Would that be a reason for the negative pregnancy result?

Hi,

Welcome back to icliniq.com.

Do not worry. Regestrone does not interfere with a pregnancy test. Urine pregnancy test measures hCG (human chorionic gonadotropin) hormone different from Progesterone (Regestrone). So the result is very reliable. So now, stay stress-free. Your period should come in a few days. Once you start menstruating, you can decide on the contraception you want to avoid unwanted pregnancy. Any doubt or query kindly get back to me. Stay safe. Regards.

Same symptoms don't mean you have the same problem. Consult a doctor now!
