Hello. Welcome to hcm.
See if you have any of these symptoms:
in abdomen,bleeding through vagina,diarrhoea
which is watery n more than 3times already,feeling dizzy,thirsty.
If yes to any,you should rush to er. It might be food infection only as in pregnancy
,your defences might decrease. If you can manage,you can wait till tomorrow and take a course of antibiotics.
All the best
