i'm 37 weeks and 4 days and i am having extreme headaches which the doctor gave me hydrocodon but that's not even helping, well i'm having extreme pain in my pelvis. is that because it's stretching to make room for my baby in the next couple weeks? or what? it's so painful i will just lay in bed having to switch from right side to left side about every 10 minutes to lessen the pain. i'll lay in bed from about 10pm till about 6am and then finally fall asleep about 6 and sleep till 1. i know i'm not getting enough sleep. could that be a reason for my headaches?
