Gas Issues or Something Else?

Saturday and Monday night I experienced pain/cramping in the middle of the night. On Saturday I had crawfish for dinner and Monday night I had taco lettuce wraps. Each were mildly spicy but I've had greater spice in my first and second trimesters. I never experienced pain/cramping until the last few days. To make matters worse my little person starts moving like crazy when I'm in pain. This might be TMI, but I poop about 15-20 minutes after the pain starts. Usually in the morning as well. I'm 32 weeks. Has anyone experienced something similar during their last trimester? Does this just sound like gas issues?
