I'm on Ava birth control and I have been for several years before that I was on Noriman. The last 6 months of the year I've been seeing my boyfriend with lots of baggage and issues (ex wife and two kids, codependent mother that wouldn't move out etc) I've picked up on his stress and have had absent periods for roughly six months. It is making me put on weight. Apparently this is called Amenorrhea. I have always been regular up until I met him and dealing with his stressful life and all the arguments has done this. I don't know how to bring it back... I eat pretty healthy and hearty, do the minimum exercise but still my body seems to not get periods. One day I'd like children so hope it doesn't affect my fertility. I have done regular pregnancy tests and definitely not pregnant so that is ruled out.
