husband has the flu 😅

T🌸
So I'm pretty sure my husband has the flu. He went to the doctor yesterday and tested negative but the doctor told him 20% of the time you'll get a false negative and she thinks he does have it, so to keep an eye on his symptoms and if he gets worse to come back so he can get an excuse and not spread it around. He feels worse today but didn't go to the doctor because he had some studying and homework to do. 
That being said, I've only had the flu once, when I was a kid and I don't remember what it was like. I'm 11 weeks pregnant, so what are some things I should watch for?
I'm going to call my midwife tomorrow and let her know I've probably been exposed.Â
