Could i have listeria?

Stupidly & out of hunger ate a deli sandwich yesterday & felt fine after , but woke up this morning with gas & diarrhea. Looked up symptoms of listeria & diarrhea is one ! Now im worried . Do u think i could have it? Im thinking of calling my nurse in the morning (forgot to add that i am currently 8 weeks pregnant)

Also forgot to add , i did eat pizza lastnight as well & about 10 mins after i was done i started having an upset stomach but never felt the urge to use tge bathroom so i never pooped afterwards until this morning. So im thinking it could have also been from the pizza
