When is your next appointment? Or maybe just call the office in the morning and ask them about it if the pain continues after you're able to get home and relax.
I have been drinking water all day and I tired Tylenol because of my back and nothing worked. I can't relax in a bath or lay on my side because I am work :/
My doctor tells me if this ever happens try soaking in a warm bath, take tylenol, and drink about 3-4 glasses of water. Also try lying down on your side. If you start having contractions every 5 minutes for an hour, go straight to the hospital.
