Normal or not?

I am currently 37 weeks. I have a sharp pain on the right side of my belly. I feel it more getting up or sitting down and sometimes when I lay on my side. Its even pretty sore above my belly button when I touch it. LO is still very active and moving and when she kicks that spot its pretty painful. Is this normal? I feel fine otherwise and she is still active, a little less but I'm sure she's running out of room and getting ready for her arrival. This is my first baby. Should i be calling my doctor ASAP or just wait until my appt Tuesday morning????
