So I had a blighted ovum and miscarried October 8, 2015. My period was scheduled for the 10th-14th. Since I was miscarrying I bled right on into the 10th and stopped bleeding on the 14th as my regular period normally would. My husband and I had sex once during my scheduled regular ovulation and my period was supposed to start the 10th of November, it is now November 18th and I still haven't started..I've had weird cravings for things I despise and a touch of heartburn and tonight I threw up. I've had some tummy irritability like I'm constipated, only I'm not constipated at all. I took a pregnancy test November 14th and it was negative so now I'm stuck and stressed out about what's really going on?!
