Any ideas to help start this process 🤦🏽‍♀️

I'm really getting overwhelmed and just ready. I'm 38 weeks & 1 day and was in the hospital yesterday for cramping and back pain. Unfortunately I'm not dilated, and the nurse said I'm "thinning" not sure what that meant but she didn't give me a percent or anything like that just said my cervix is still closed. My bf and I have been having LOTS of sex, which isn't working from what I can tell. I know she should stay in there and cook for a little more but is there ANYTHING I can do to at least start the process quicker? Any tips? Please and thanks, I'm trying to keep it together but all these false crampings and what not are really starting to make me sad. Thanks ladies ❤️
