Severe stomach pains

Girls I really need advice here.

Basically since last night I’ve not been feeling too good I’ve had a lot off diarrhoea (sorry tmi) but also I’ve been having really bad on and off stomach pains😫 everytime I have one my tummy doesn’t tighten though so I thought ‘they’re clearly not contractions’ but they are so bad I’m doubled over in pain... any ideas?
