Pending birth

Hi so I turned 32 weeks Friday. That morning my water broke during sex. Went to the hospital my cervix is 4cm 75 effaced. Not having contractions already had all courses of betamethasone and magnesium. They said if I dont go into labor at 34 weeks which is the 7th i will be induced. Has anyone water broken early but wasn't in labor. How long did you stay pregnant. I'm on iv fluids and antibiotics. When I do have a contraction his heart rate dips then comes back up. I'm not due till March 20.
