Hi I Am Shruti From Goa. I Am 38 Weeks

hi i am shruti from goa. i am 38 weeks pregnant. my problem is doctors saying that they cannot recognise the position of baby due to my obesity. i mean my belly fat is more than expected. they r saying that by now the head of the baby should come down. but the baby is not engaged yet and the normal delivery is difficult. and i dont want czarian operation to be done . i want normal delivery. my question is what should i do to bring the baby in right position?
