I was the same way , i told my doctor he request to go to the er if it got worse i did but they took forever like 4hours waiting so i left and took A Tylenol. But like a week later i went and my obgyn said everything was okay he didn't see anything wrong but i seriously got scared you should get checked. Asap just make sure everything is okay.
No, it's not normal if you're in that much pain... I'd go in and get checked. Cramping is normal but not if you are in serious pain.
