In early preg. have a smaller hemorrhage in cervix. have been throwing up pretty badly. stomach is a little sore. could this hurt the hemorrhage/preg?

No.: Even the most severe nausea and vomiting in pregnancy won't cause a miscarriage from the pressure of the vomiting. It may make you have some more bleeding (because of the subchorionic hemorrhage) - but it won't cause you to miscarry. But there are a lot of medications that can help to treat the nausea and vomiting you should ask your doctor about.
