So June 22 was my last period my next one was supposed to be august 5 which passed august 6 I went to my gyn appointment she gave me a blood test next day results came back as (<1) which means negative but most GYN’s told me it could indicate very early pregnancy everyone lab testing is different however I have been having cramps , I been vomiting , tiggling boobs I know my body very well today just now I went to go pee I wipe myself in its light pink discharge I do have PCOS and irregular periods so do you think it’s my period or implantation bleeding ? Or could it be very early to tell ?
