Stomach pain during pregnancy.

Ashley
I had a miscarriage and d/c in August I am now pregnant again 7 weeks tomorrow I went to the er a week ago cause I have been having a lot of pain. They said I was dehydrated and needed to drink tons of water which I have been doing they also said it was my uterus growing and said it was upper-gastric pain and gave me Pepcid to take which I have to been taking. They did a ultrasound baby looked good heart beat was 113. Even though I'm drinking tons of water and taking Pepcid I still continue to have stomach pain. I'm trying to wait till I see the doctor on the 25th. Has anyone had this problem and did it get better?
