it's a common side effect of the depo shot to not get a period at all. you've been on it for awhile now so i wouldn't be too concerned unless you were late getting the last shot. when i was on the depo shot i hated it! i had more pregnancy symptoms then when i was actually pregnant with both my sons.
on depo. period symptoms w/o bleeding. i've been on the depo shot for a bit longer than a year now and i love it. this past week was my week before my next shot and usually i have bleeding then but i haven't. i've had a thick white discharge cramping and other period symptoms and i've almost fainted/ had vertigo a few times. i've never had this sort of thing happen but i've done pregnancy tests both at home and in the lab i work at so unless it's too early to tell i'm not pregnant. has this happened to anyone else?
