I was on Junel 1/20 for a couple
of years, then went on
Yaz for a month last April (I was living
in Germany and the doctor ok'd it, even with my questions about health concerns). After going off Yaz, I have never had my period again and hadn't had it before that since February.
I (stupidly) did not really think it was an issue until right around Christmas when my mother said I should get it checked out.
