C-section scar hurting..

Tris
Anyone else pregnant with their second baby and experiencing c-section scar pain? I'm 11w 3d now (but baby was measuring 6 days ahead at last ultrasound). The pain comes and goes, is typically sharp (but can be a little achey), and is located right along my c-section scar from two years ago. I'm hoping some other mamas can put my mind at ease that this is normal :)
