I ve been having breakthrough bleeds for the past 4 months. I had unprotected sex, but he didn t ejaculate inside me, on about a week and a half before my period was due to start. My period started 6 days late but it was a heavy period and finished about a week and a half ago. I m currently having a brown discharge, I m bloated, tired, my breasts are sore and my nipples seem darker and bigger. I took a few hpts a few days before and one day before my period started and they were negative. There s no way I could be pregnant is there?
