I'm new to glow and stopped taking my birthcontrol almost two months ago.Im not due for my period for 7 more days but had this light pink spotting that only happened once a day for 4 days and today a thick tiny bit of very light brown.I have read up on implantation spotting but I don't think it would be this long..its like a tiny pink was there once each day but then gone.Whats your opinions on this?
