on Thursday I'm supposed to be getting my period. but I've been feeling a little off.. nothing tremendous but I feel something here and there. Today whenever I go to the bathroom and wipe I see a little discharge that is light brownish. i put a little bit of paper inside, not all the way in to make sure its coming from there and it comes out not alot.. but this never happened to me.. could it be nidation ? implantation. ...
