I’m 39 weeks pregnant and was riding in the car. My stomach started to feel crampy and then it started hurting really bad probably for 15-20 minutes. It was making my back hurt and my legs a little numb. My stomach never felt like it was tightening. It kind of felt like a really bad gas bubble. I haven’t experienced any contractions yet but since my stomach wasn’t tightening I didn’t think it was a contraction. After it hurting for those 15-20 minutes I started feeling sick and ended up throwing up something I had drank maybe 30-45 minutes before and the pain went away. Could this be a labor thing or was my stomach just upset from what I drank (chocolate milk) my stomach has never hurt like that. I usually just throw up.
