Help!

Stephanie
I am 17 weeks pregnant and have horrible stomach pain , my doctor said it is normal since my uterus is attracting but my god , this is pain all over my stomach and harsh pain. 
If any of you had this pain , and ended up going to hospital any tips or anything I should look out for . How bad does pain have to be to go to hospital ? 
It hurts like an 8 , on a scale of 1-10 
I could cry ..
