Tegan - I have the same thing. I mentioned it the other day to the sonographer when I had an ultrasound and he said that most women will have a tender spot somewhere. It always happens to be where they most need to put the bloody ultrasound thingy (that is the technical term btw!! lol!). It is apparently due to muscle seperation,and nerve endings?? Funny though, Mine was on the left and has now moved over to the right!!
