When did you start dilating?

I know every woman and pregnancy is DIFFERENT so I’m asking this question just for general feedback from anyone who is currently pregnant or has been pregnant. I’m right at 37 weeks today and still haven’t started dilating. Last week, he was 6lbs 15oz so he may be almost 7lbs as of now. I must admit it was a little disappointing to me because I feel as though I should’ve started by now. This is my first pregnancy so I’m still lost on a lot of things. I was told to have sex, which I do and also to allow my husband to “stay in” because the semen helps to thin the cervix as well as eating pineapples and walking. I guess I’m frustrated overall just because I’m ready for this to be over with and I don’t want him to come out late (due date is June 29). Anyone have any suggestions or feedback?
