I'm 37 weeks pg with baby No 2 and just recent;y have been having some sharp pains inside. They feel like someone is pushing a very sharp knitting needle right up inside me. I've had them on and off over the last few weeks, ie just one every couple of days, but today I've had quite a few of them. They dont last long but they are monstrously painful when they occur.
Any ideas what they might be?
