Anatomy scan

Je

My anatomy scan is next week and I’m having such bad anxiety. Even though this is my third baby I’ve never had such bad anxiety. My second baby we had a scare at the anatomy scan for a soft marker for trisomy 18 ( luckily the cysts in her brain dissolved, so it was a scare for nothing) I just want my baby to be healthy. Two things have happened that has me nervous, I took plan b when me and husband had unprotected sex and I still got pregnant, Ive been scared that could have done something and at about 8 weeks pregnant I got the flu and had a high fever of 101 for like 3 days, Tylenol worked only a little bit, I had no idea having a fever could be so damaging at that stage so I’m freaking out now. Ugh. Anyone have reassuring words?
