you have been bleeding non stop since July? That's too long time bleeding and it's time you go to the doctor to get that check, that is not normal. You are problaby sick of anemia rather than pregnancy being that long time bleeding. Depo provera is a scary drug (I would never use that one, it causes osteoporosis) and if just give you this side effect already I would stay away from it as far as possible.

yes u can get pregnant while on the jag my freind feel pregnant twice ont he jag .

Well i don't kno if it is not normal to have your period for 3 months when you first get your shot because when i first got my shot i had my period for about 2 months......but im not a doctor so it is always best to ask a doctor!!!
