34 weeks and always in pain?

I don't remember hurting this much in my 8th month with my other two, but I'm constantly in pain, everytime baby moves its painful, and it hurts to stand, walk, sit down...I feel like my vagina hurts, my pelvis is always hurting along with my back. Belly bands do not help and my body pillow isn't helpin much either. I rest as much as I can, but nothing helps at all. I have high amniotic fluid and placenta privea. If anyone can tell me anything to help with this it will be very much appreciated!
