Depo-Provea

has anyone else had trouble ttc after getting off depo? I've been off for over a year I was on it for about 2-3 years just started having AF at the beginning of this month after 2-3 years of not having it, AF is suppose to arrive today but thought I had implantation bleeding about 5 days ago bc it was just two drops of blood and nothing more, I've had all BFN for a week now think depo just messed up my body, anyone else?
