In February this year I had a miscarriage at 6 weeks and 5 days. I had passed the baby but not the sac so I decided to wait until the sac miscarried naturally but nothing was happening so I had a medically managed miscarriage in March which involved them inserting tablets to induce the sac to come out. I bled for 6 long weeks with that and eventually stopped about 6 weeks ago...I ovulated on the 9th of May and I'm not on any contraception so I've been having unprotected sex all month. I've read over and over again that it takes 4-6 weeks for a period to return after a miscarriage but I thought that if I ovulated two weeks after I stopped bleeding from a miscarriage then surely my period would be due two weeks after that right? Well, I haven't had my period and every pregnancy test that I've done has come out negative. I've had cramps, bloating, gas and a little nausea but not tender boobs which I usually get before my period and they were the first sign of pregnancy I had in my last pregnancy.
Is there a chance I could be pregnant?
