Usually i will have some brown dishcarge for a couple days after my period. It has been a full week, almost 2 now after my period and i've started having them again. But only this time the discharge is not thick like usual, its very thin. (this may be gross, but it looks like chocolate milk) I am now having cramps with them as well. I dont know if this has anything to do with it, but too after my husband and i have sex, i also have brown discharge. Is that normal? and what is causing this?
