Not cervix related

I’m sorry if this isn’t the place to ask/vent.
I asked my fiancée to make me a sandwich for my late night snack, I have gestational diabetes. After the last bite it had an odd taste but I still ate it. Later on my tummy felt odd and I asked him to check the cheese. There was mold on them right on the corner. I am freaking out!! I’ve tried to do everything right in this pregnancy after two prior losses and I’m so scared of listeria, I don’t want anything to happen to my baby. I had 1 pre-sliced pepper jack cheese. I’m not currently having any symptoms its 9am and I had the sandwich at 9pm/10pm
