Intense cramping

Darien
Okay so i have been having INTENSE cramping for 3 days and it hurts a lot.): and i have braxton hicks, which are just uncomfortable.. But then i have the same tightening feeling but with even more pain.. It lasts for a few hours.. And im afraid to go to the doctor because what if it stops when i get there?!)): advice? Ideas? Im just so confused..
