So I had a long period from 9/5-9/14. I was supposed to start AF again on 9/27-9/28 (23 day cycles since implanon removal 8/14) and got a very faint positive last Saturday. I still haven't started af but not seeing faint lines anymore (testing every morning since).. Slight cramping, fatigue, mild back aches, heavy sensitive breasts... What's going on?
