Help! Freaking out! Do I have listeria?!

Meredith • 🌈 👶🏻 November 2019 - praying this one is sticky 🤞

So I’m 4 weeks today and yesterday I ate buffalo chicken pizza with blue cheese without even thinking. I called later and found out the blue cheese was pasteurized and it was all baked in an oven before I ate it but today I got diarrhea.... is this unrelated or did I screw things up? My last pregnancy I miscarried at 8 weeks and am so scared about it happening again.
