HELP!stomach problems

my stomach has been HURTING so bad latley. it like once a day for at least one hour, it makes me feel like i’m going to pass out, throw up and/or over all horrible. i don’t take medication for it, bc i don’t know if i should. it can make me literally scream in pain, or just curl up in a ball and cry. i don’t want to go to my doctor for it. it’s been happing for a couple of weeks. if it comes down to having to go to a doctor i will. but any tips? i’m really scared.

*i can not be pregnant. it’s not a possibility*
