How do I know if I have food poisoning?

So yesterday I got a carne asada burrito and a few hours later at night I started getting these cramps and went into today, they hurt but it was alright then a few more hours passed and I started having extremely bad cramps to the point I’m grabbing my stomach and curling into a ball(it hurts so bad) and then I’m having diarrhea, and im constantly going back to the toilet 😩

Some people said the color matters but it’s like a brown/yellowish

I’m also having really bad body aches, from my head to my entire back & I have a headache, my eyes hurt from this & the body aches is making me feel so crappy, I don’t have a fever tho. Also sounds are very sensitive to my head right now, I just feel horrible right now. Could this be food poisoning? Or maybe the stomach flu? Cause they share almost the same symptoms 😩

all I know is I have a 1 year old I still breastfeed and sleeps with me (he wont sleep without being in my arms) and I have a 3 year old I don’t want to give them the stomach flu 😩

So I’m hoping it’s food poisoning
