Had a light period for over a week, with two days in particular, very painful and a little heavier. A day after it was over my breast became a little firm with the nipples being sore, this happened three days along with me having three spells of extreme horniness. I came of the depo over year and this has been my third period since, but its my first time feeling this way even though the depo had me feeling pregnant for almost a year after. Can someone tell me whats going on with me? already took two pregnancy tests both negative.
