How to prevent diarrhea (school tomorrow)?

giraffe

First I was constipated for a few days, then today I had diarrhea (I think from a tablespoon of olive oil I used as a natural laxative)

I'm not sure if its done running its course (I haven't had it in a few hours, but my tummy is still rumbly)

I have to go to school tomorrow, but I'm scared of having an accident...
