Really bad abdominal pain.. any advice?

I was curious if any of you have or have had bad abdominal pain even when sitting/lying down?

Yesterday my daughter had a recital and it lasted about two hours with an intermission which I got up and walked around. I noticed my Braxton hicks started getting stronger but this time were accompanied with pretty bad upper abdominal pain around my waistline. Afterwards we had dinner, I chugged water but the pain steadily got worse. I got home and really struggled sleeping from the pain but it had eased up compared to what it was dinner. Today I barely made it through church without the pain coming back, especially worse during my Braxton hicks.

Curious if any ladies have had this and know how to make it less intense. I am beyond uncomfortable and dont know what to do. Even lying down I cant get rid of it completely. I'm 34 weeks 3d and baby dropped about 2 weeks ago (maybe its just baby weight pulling on my muscles)
