honestly kind of scared

So we keep our extra Parmesan cheeses and stuff like in the little packets from dominoes in the same drawer as we do our silverware I woke up this morning to eat some cereal and saw that they were torn into but didn't really think of it until my husband mentioned that mice had gotten to them. I'm 31 weeks pregnant and also have been throwing up the last two days out of nowhere? Do you think something could be wrong with me from the mice?
