Iv not had a period in over 7 weeks.. no idea when or if i ovulated.. negative strip test this morning.. went to the toilet this evening and when i wiped there was pink watery blood which i thought was my period finally starting so i put a tampon in and a few hours later when i took it out there was a tinyyyy amount of thick brown discharge/blood on it and that is all. Nothing since! Iv been googleing and sounds like implantation what do you all think??
