Even if ur on the pill. I saw ur post, and thought Id answer because i used to be on the pill for a long long time. id say if it stays irregular then check with your doctor. it was always a sign with me that something was wrong if thing stayed irregular.

This happened especially when she first started it and when she stopped taking it, to become pregnant. So I shouldn't think it was a cause to worry, but see your doctor if it still hasn't stabilised I would say. WA
