pain in upper abdomen


For the last few months I've had a pain in. My upper right abdomen, just below my boob. I have an appointment on the 1st with my obgyn. But the pain is slowly getting worse every day. Painkillers do not help at all! Should I call the out of hours number, make a doctors appointment or just wait until the 1st? On a scale of 1-10 it's about a 4/5 and more of a dull ache which sometimes, more often recently is painful. Mostly just really uncomfortable, and with baby kicking its not fun! 33 weeks pregnant tomorrow
