Worried

9 weeks today all pregnancy symptoms are gone .Have had severe lower back pain all day called my Dr they said they couldn't see me today but to go to er if it gets worse. Well the back pains a little better now but having pretty bad cramps both sides of abdomen my SO is at work until 430 I'm going to the er then, so afraid they are going to say im miscarring again. Anyone have these symptoms and still end up with a healthy baby?
