Shooting pains!!

Jenai • Keep Calm I`m Having a Boy

I'm 36weeks and 4days pregnant

I went to the Dr day before yesterday and was told I'm dilated to a 2 and 50% effacted. The pains are shooting for my back to pelvic area. It's starting to hurt to walk and sit up. I have done hot baths for the last two nights. What can I do to either progress labor or help with the shooting pains. I am allergic to ibprohen and generic brand
