i just found out recently that i am pregnant. i haven't had my first doctors appointment yet because the doctor i go to couldn't get me in until 3 weeks from when we called. my question is my friends and i had planned this graduation trip to Chicago. were going to be riding the train to Chicago and going to navy pier, six flags, the bean, all that stuff. ill only be between a month and a half to two months (since I'm not exactly sure when my due date is). is it safe to ride the coasters at that stage in pregnancy?
