bug bites

Andie
Up until recently, I had a cat. I had to give her to a friend because my bf's allergies were getting too bad to keep her. About two weeks before I have her away, she got out of my apartment twice and stayed out for 2-3 days at a time before I was able to catch her and bring her back in. She must have gotten fleas while she was outside cuz I've seen a couple in my apartment and have gotten a lot of bites. Does anyone know if flea bites are dangerous while pregnant??
