Long Cervix???

Marisol
I am a FTM going on 39 weeks and I went to the DR today & he told me that I have a very long cervix and that the baby is still high up. He has yet gone down into my pelvis. DR is saying that I have a 90% chance of having a C-Section, I want to avoid this unless it's medically necessary especially since my due date is not until the 16th. Has anyone have had this happen to them before & if so is there anything that I can do to help the baby makes his way down into my pelvis?
