Today I have an appointment with my doc for a follow check up Due to preterm Labor , about a week ago I was in the hospital & Had to go through all the meds from keeping my daughter from coming . I had a question for thoes who Have Been through This , what do your doc do when you went for a follow check up ? I mean I know they'll check if more dialation , would they do an ultrasound also ?
