So this is all new for me and sorry for TMI - for the first time ever I noticed light brownish spotting for couple days about 6 days after my last period (May 20th) and now since last 4 days I've been having similar but a little darker brown mucus spotting everyday. I should've had my period today but nothing so far. 2 pregnancy tests done so far negative. Does this sound like Implantation bleeding??🙈🙈 TIA!
