Suffering From Cough And Soreness In Stomach

I am 33 weeks pregnant and getting over a horrible cough. My tummy is so sore from so much coughing, like I've done a million sit-ups. Luckily I am getting over my cough, but when I do cough or sneeze, it has now gotten excrutiatingly painful. Especially on one specific spot on the right side of my belly where my baby lives to stay. It's like I can feel a foot r some body part digging into me, like a stabbing feeling, every time I cough or sneeze. It is incredibly painful. I can't take it. She is already a big baby, over 5 lbs, expected to be about 9 lbs. I have no idea if her size has anything to do with it. That part of my belly just stays sore constantly now. Is there anything I can do?
