What would you do?

I'll be 36 weeks Saturday, this is my 5th baby so I know they tend to come faster. I've been having extreme pressure and pains that I wanna cry because I can't handle it, its not contraction type pains its just real bad pressure and pelvic pains. I have to lay down in order to relax my body for it to stop, or im on my knees rocking back and forth trying to get comfort. My husband said I should call my dr because he sees that I'm crying and miserable. I see my dr Thursday so I wanna wait till then.....and baby has been moving non stop like crazy she gets in these positions where I'm saying oh God ouch. I know your body preps for delivery but when is too much, too much to handle before your not able to get up and do anything?? Anyone else? I have little kids to take care of so I can't lay in bed but I lay on my couch like a sloth whenever I'm able.
