I've been having what I thought was muscle spasms in my stomach off and on all day.. well 5 minutes ago I got up and had another one and it was so bad I doubled over and started breathing like I was in labor. it lasted about 2 or 3 minutes (shortest muscle spasm ever). immediately after it was gone I had to poop and now I feel sick to my stomach. my mom said maybe Braxton hicks and to time it. but I'm debating if I should call my doctor because my lower back is starting to hurt. I don't want to go and be told that it really was a muscle spasm or I'm just freaking out over nothing
