My boyfriend and I are not really trying, but I havent gotten any answers yet I am on the depo and got the first shot in feb. Ive been on it before so i know how My body reacts. I was on antibiotics and had unprotected sex twice last weekend on Sunday with My bf. I am not supposed to have My period until the last week in April or the first week in may. Ive had some nusea, back aches, and tenderness on My abdomen. im also moody as crap.Since the end of the dayy yesterday, ive had some pinkish discharge. Like a very light period, and im thinkin it could be the implantation bleeding n it looks like Its going to be done by the end of the day tomorrow.Idk. And I want to take a test asap just so i can be sure. When can i do that? Could I be pregnant?
