hii, i recently got off the depo shot about 3 weeks ago and i was only on it for 9 months and during does 9 months i would still get my period about 2 wedks before my next shot was due. now that i am off the shot i bleed after intercourse, its not heavy bleeding its light and it lasts for about 4 days. im wondering if thats a side effect after getting off the shot or should i be worried? this has never happened before.
