So I'm 39 weeks tomorrow and my husband and I were DTD and he could go as deep as it got very hard and hurt me. We've done it that position many times and its never been an issue before. Well at 38 weeks I was 2 cm and 80 %. membranes sweep happened and contractions but no labor yet. but I think I can feel it's soon. Was it the babies head he was hitting?(or water bag) also she said his head was engaged if that helps
