Braxton hicks?

Waynell
Hello everyone,
Last night I went to the hospital because if stomach tightening that was so uncomfortable. It started after I went for a walk, it would not go away for about 3 hours! I kinda freaked because I never experienced this with my first pregnancy. It was hard to get comfortable anywhere, it got to the point where my stomach would tighten then I would get shortness of breath from it. I was contracting when I got to the hospital but hey said it stopped right away. Kinda scary I'm only 25 weeks. I do not want to go into labor. What really made me mad was that the doctor did not know what was going on with me. I was clearly contracting, but my water was not broken or no infection either. I just wanted to ask if anyone else went through this? Was it a big case of Braxton hicks?
