My wife (7wks pregnant) used the toilet shortly after she cleaned it with bleach. Vagina was exposed to bleach odor, will it harm the baby? Thanks

No. Mom and baby should be fine. The cervix is closed tight and baby is not affected by any fumes or things like that from the outside.
No. Baby is not affected at all. It is actually a very good cleaning solution that is not harmful. Kudo's for keeping the bathroom and toilet clean and free of germs. But humans can actually bathe in dilute bleach solutions, and we sometimes do this if there is MRSA that keeps going around a household. She and baby will be fine.
