Well, I would assume that if there was an accident of any kind and trauma to her belly that she would make an appointment to get checked out just to be safe. If not though, possibly cramping, maybe bleeding, and if it is really early like that possibly a m/c. This seems like a really odd question to me!! Did something happen?
If you are being abused, you need to contact an abuse hotline and hightail it out of there. I don't care if it is his baby or not. If he'll abuse you, he'll abuse the child!
It would take a lot of trauma for you to miscarry, but it is possible. You need to go see your doctor and BE HONEST with them. Don't give them a B.S. story about falling down or running into something. They'll HELP you, not judge you. Abuse is not YOUR fault. It's someone's dominance over another human being.
By the way, there are safe homes you could stay at and they'll help you get on your feet (like education, finding a job/career, finding a home, etc.). So none of this stuff about "I don't have anyplace to go!"
I fell at about 6 or so weeks pregnant, right onto my side and hip. but all is well, I'm 18w now. I agree w/ JoyRenee~ If your being abused you need to contact help. it'll just happen again.
