Pain at 34 Weeks

Yesterday I experienced two instances of pain on along the right side of my belly. Each time it lasted about 4 minutes and they happened within an hour of each other then stopped. The pain was more intense than a period cramp for me and I found it hard to move at all while it was happening. I’m not sure about the “stomach tightening” that people describe contractions as because I had a emergency c-section with my first.

Has anyone else experienced something like this? If it happens again I’ll call my doc, but I have a appointment coming up soon.
