Pressure!!!

What are you ladies doing to try and be somewhat comfortable? Or at least not miserable. I have been having so much pressure it feels like I am sitting on a ball, making everything from my upper thighs to lower abdomen hurt/uncomfortable constantly. Only relief is to lay completely on one side or sit tipped way back on my but. Even that is getting more and more uncomfortable as the day goes on... 38wks 2days, no show or water break, cramping and BH.
