well every person who gets pregnant worries, but ive been there done that with those pains, wait for your ultra sound,and try not to get too stressed i heard that could cause a msiscarriage. the pains are normal though. if they get way way way too intense then go to the hospital, that happend to me once and they put me on bed rest, just to be safe, but i was showing no signs of a misscarriage.. my cervix was closed, they also drew blood, did an ultra sound and evryhting was normal.. i think getting your first ultrasound will help out..
