Hi Ladies!

Im 37wks preggys i have been sleeping only on my right hand side (the only comfy sleeping position) but two days ago, ive been gettin this sharp pain on my right hand side of the body below the ribs and just on top of my hips. It comes and goes but wen it comes its sharp as if someone is pinchin it

Does anyone have any idea of what it is? any advice? or is it just part of the aches and pains of 3rd trimester
