Hi, I had sex on 30 August, we had unprotected sex, and last minute we used a condom, hence he did not ejaculate inside me. I have been spotting brownish blood for 4 days (September 5-9) My periods were due on Sep 11 (I have never been late of missed a period). I have taken 2 test by now, both negative. I am getting period cramps but no period..
