worrying

Stephanie
So I'm late 5 days 
I just (10-15 minutes ago) got a really bad bellyache it felt hot burning my belly was gurgling and it hurt like hell I went the toilet incase it was either one and nothing I sat there in pain and nothing happened 
I haven't really felt that pain before 
I'm so worried 
Does anyone know what it could be? I will be going the doctors if it happenes again
