I don't know exactly how to explain what's going on except that. I was pregnant 6 weeks ago, but ended up having a miscarriage, but got pregnant again, and then 7 days ago bled for 3 days started out small, but then got very heavy with a excessive amount of blood clots which immediately made me very worried. I didn't go to doctor though, because I knew it was just another miscarriage, and I have no medical insurance so it's difficult for me. I get huge bills from hospital. So a couple days I did go to the hospital to get something rechecked completely irrelevant from the reason I need you're help. I also got an ultrasound, and blood work done to check what was suppose to be my baby. They didn't see nothing although while my boyfriend was watching my ultrasound be done there was heat signals everywhere, but no sack anywhere to be seen. There is only heat signals when a baby is in you're stomach. I am worried, because my stomach is uncomfortably hard, almost like the feeling if you've had a full meal, or have to go to the bathroom bad. It kind of hurts too, so I'm hoping that doesn't mean I could be having a tubal pregnancy since that also wouldn't come up positive at all.
