I am 36 weeks pregnant and expirencing a constant, make you throw up, can't sit still pain in my back (right side) and in my pelvis.

Had the same thing a week ago and midwife told me to take a shower a tylenol, two gravol and go to sleep. It went away.

I'm worried that it's something that's not supposed to happen, even though she said baby is probably moving into position.

Any thoughts? Should I go to ER or maybe a chiropractor?

Edit** turns out I had kidney stones
