Its hard to get used to and very unsettling I know. But I had the cramps almost all the way through my first trimester. I used a heat pack and if they got very bad a couple of Panadol helped. Try not to panic which is easier said than done, but your body is making some pretty huge changes to allow room for bubs. I used to think the more it hurt the more the baby was borrowing in nice and deep and safe. It gave me comfort. It will back off...
