My last period started March 13. My partner and I had unprotected sex on March 24 and the next day I felt it in my bones that I conceived. My period never came this month just as I suspected, I’ve never missed a period in my life. I took 6 at home pregnancy tests which were all negative. I went to my gyno Tuesday and got a blood test which was negative as well. Yesterday I had no bleeding but a large bloody clot passed and nothing else. I showed my partner and he said it looked exactly like what happened when his ex had a miscarriage. I have had horrible cervix cramps and back cramps which never happen. Is this possible???
