Since yesterday I've had a sore tum. It's very low down, around my public line and it feels really tender. I've had the other pains, you know, like period pains before, but this is different. It feels really heavy and sore, and I've been getting sharpish pains in my lower left hand side occasionally and walking is uncomfortable. Anyone else suffering/have suffered and can offer any advice on what this is? I'm 15 weeks today.
