Listeria??

Before I knew I was pregnant I ate raw fish, raw oysters, soft cheese, delimeat, etc. It wasn’t until I found out I was pregnant that I stopped, (with the occasional piece of smoked salmon roll off my husbands plate) I’m worried that I have listeria.

I have a sore neck, throat, and stuffy nose. It’s basically a cold, but I’m worried regardless and I want to go to the ER. I read listeria can stay in your system undetected for months, I puked this morning but it’s pretty normal for me this pregnancy. Please help, I’m so stressed out.
