You still have time. I'm due on17th and don't feel anything yet. I'm in UK they don't really check before 40 weeks to see if you dilated
You can try evening primrose oil capsules. Take two orally in the morning and at night before bed take two vaginally. The oil is said to help soften the cervix.
I am also due the 12 with my second. My first I was 1 cm the day before. This time I was 1 cm Friday. For my body it means nothing since I labored very quickly. I am anxious for this baby to come out, but another part of me knows the longer he or she cooks the better! Let their brain keep developing and gaining weight etc. they will come when they are ready <3
