So I've recently had a miscarriage in late January and had unprotected sex in late February. I had my period a few days later which was very heavy and abnormal, alot of cramps which I never have, I was nauseas. It took alot out of me. I took a pregnancy test afterward which said I wasn't pregnant. I have been really moody for a few weeks and hungry all the time. I know each pregnancy is different. Before my breast were tender and I was always hungry and urinated frequently but when I found out I was about 5- 6 weeks along. I haven't had any of the same signs but my period is always 28 days even after my miscarriage and I never spot for almost a whole day before normally I will spot for a few hours then it will become very heavy. This time I've been spotting off and on for two days and still haven't started. I just want to know if there is anything other then being pregnant that could be possible. I took a pregnancy test about 16 days ago which came up negative but I know most the time they aren't very accurate until 5 days before a missed period. Any ideas?
