Not to scare you but since you are preggers I would follow the state guidelines below. I would also take the extra step and not eat any of the eggs until a report is back but this is just my opinion... One summer we had one that kept trying to "attack" us during the day. We tried to swat it out of the air with a broom (very futile) and it flew away so we didn't report as all we had was a story, not the sick bat.

Bats
Bats are among the dead or sick wildlife species that people find most often in Utah. And that isn't good. McFarlane says bats are the primary carrier of rabies in Utah.
"About two to five bats that are found in Utah each year test positive for rabies," she says. "Please keep in mind that this is a very small number compared to the actual number of bats that call Utah home."
If you see a bat that's behaving unusually, such as flying during the day, or you find a bat inside your house, or you think one may have come in contact with a child or one of your pets, please call the nearest DWR office immediately.
McFarlane says it's common for cats to capture or chase bats, especially at night. "We encourage you to keep your cat's rabies vaccinations up to date," she says. "Keeping its vaccinations up to date might be the difference between enjoying your pet for years to come or having to put it down because it contracted rabies."
