So I’m recently 3 days late ... but yesterday I starting spotting brown discharge.. now there was nothing when I went to the bathroom or when I wiped, I only saw small spotting in my liner.. now I’ve never had this happen BEFORE I get my period .. it’s usually after when I’m finishing my last days, so this is strange for me... I only got brown discharge when I started birth control pills but I’ve been off of them since sept and have had normal periods for oct, nov, and dec... I’ve heard of implantation bleeding ? Could this be it?? I also took a test but it gave me an invalid result , I guess I did it wrong ?
