I miscarried on August 16 and it lasted a week. as stupid as I was i should of knew I ovulated but their was little blood and that was part of ovulation. But I didn't have sex since the beginning of August. I thought you had to have a period to get pregnant but apparently not. my period still has not came and I'm having sore boobs on and off hot flashes and getting light headed sometimes. the doctor said on August 30th I should start my period on September 2st. so why would my breasts hurt
