When I was 3 month PP I got my period back on a regular cycle for 3 or so months and then in May I was 9/10 days late. My next period was normal and now I'm 11 days late. I really don't think I'm pregnant but I am concerned that I won't be able to get pregnant when I want to (in 6 months or so) since now my cycle is irregular. Has anyone had this issue?
