I m in 39th week. Since night before having vaginal and lower abdomenal pain.. Yesterday doctor did internal check but baby's head is still not down.

EDD 1st August. Doctor said chances are low that by then the head will fix by then. Pain Reason sited by doctor is that my pregnancy weight is high.
Elders saying since didn't eat much of heated things so late, etc.

Please advise what can be done for head to fix and go under normal delivery.
