Hi, I have taken norethisterone tablet twice a day for three days from march 10 to 12 when I was expecting my period in 12th. But I didn't get my periods yet after a week. I had some brown discharge before taking the tablet and I had some brown discharge even now but no periods. I am not pregnant. I usually have regular periods. Even if I take tablet usually get periods after 2 days of stopping it though taken very rarely. Please suggest this is my first time periods getting this much dely. I am 30.
