I wouldn't wait more than a few hours if your water breaks... With my 1st son my water broke before feeling any contractions. I didn't go to the hospital until 3 hours later. With my 2nd the contractions started at 2am, went to the hospital around 6am. I was only dilated to 3 or 4 so they didn't admit me. I went back like 6 hours later when the pain was too much, was dilated to 7 so I was admitted. My water broke a couple hours later.
