Hey guys, I recently did a procedure with Stork and I also took clomid to increase my chances on getting pregnant, my period day came and I didn't get my period for the first three days of my projected period and I took a pregnancy test and it was negative. On the fourth late day I started bleeding which was the 30th day cycle and I never had my period on the 30th day....is it a possibility that I can be pregnant even though I'm on a late period
