I took norethisterone & period came 3 days (16/04) aft i stopped, but has not returned since then. 2 weeks brown discharge starting 22/05. pregnant?

Missing info.: I would need more info to answer that. Have you had sexual intercourse in the past month or so? Why you were on norethisterone? It sounds like you aren't ovulating & there are 2 likely reasons. One is a hormonal imbalance that is also causing irregular periods. The other is pregnancy. If there's even a small chance of pregnancy, then please get a pregnancy test. Best wishes.
