Me and hubby recently decided to TTC. On my last day of ovulation (20th March) we did the deed. 7 days later I noticed my boobs were sore (this lasted a few days) and I also had light brown discharge. At the time I thought this was implantation bleeding but 7 days later it is still happening. The flow got dark and watery, and just now I had a little black rubbery stuff in my pantyliner which I think could be tissue. Im going to do a pregnancy test, as my period is due tomorrow. I just have a bad feeling. Had this happened to anyone else?
