I am 7 months pregnant and my husband sleeps with a fan on at night. I just looked at this fan up close today and didn’t realize how dusty and dirty it is. I’m worried now because we breathe in that dust every night. I normally wouldn’t care if I wasn’t pregnant but could this harm the baby?

All of our scans have been good so far and the baby seems to be healthy and kicking. I’m just nervous. Am I over thinking? I started cleaning it this morning and will finish after work today.
