Frequent Braxton hicks at 24w5d -- help!

So of course I'm out of town and this happens on a weekend. Starting yesterday, I've had Braxton hicks in and off all day. I never have more than 4 in an hour, but my belly has been tight a lot yesterday and today. They only go away if I lay on my left or right side. I drank 94 oz yesterday so I know I'm not dehydrated. I didn't have any overnight unless I stretched to change position. I'm calling the nurse line tomorrow, but I'm in Nashville visiting family so praying it's nothing serious. After 4 miscarriages, this is really freaking me out. Any ideas on how to make them go away? Or anyone know why I'd be having them a lot all of a sudden? I rested almost all day. So frustrating as I want to be with my family and enjoy them.
