Weird burning sensation in between inconsistent contractions? Anyone experience this?

BOBBIJOKULENEK
Have been having inconsistent contractions a lil over a week now. 5th pregnancy last one was emergency c section. I'm having a strange burning and pulling sensation in between contractions. Almost 39wk. I have never gone full term. Left a message with doc I'm sure it's normal with all the extra weight. Anyone else feeling this?
