i get a pain in what feels like my cervix which is sharp....i tell my DH it feels like i've sat on a knitting needle. I have had it for as long as i can remember with this pg and put it down to bub headbutting me but i dont know if 12 weeks is way to early. I got the same pain with my 1st pg but not until i was very close to my EDD. HTH. if your worried get checked JIC it might help ease your mind
