Hip pain after waking up and can't sleep.

I'm 16 weeks and 5 days and it takes me forever to fall asleep. Then, my husband will wake me up accidentally and it'll take me 4 to 5 hours to fall back asleep. The past three days I've woken up with extreme hip pain. After the first day of hip pain, I slept with a pillow between my knees and legs but I've still had extreme hip pain. Any relief so I can actually sleep? Help!
