Nervous about gender

Hi. So I am 8 weeks +5 today and going for first scan. On June 1 I’m going for the Sneak Peek Gender blood work. It’s 99.9% accurate with 100% guaranteed. My husband wants another boy and has been clear he will not be happy with a girl. I told him his sperm decides. Not me. I’m scared it’s a girl lol I know he will love our kid no matter what but won’t be happy during this pregnancy. How can I show him little girls are great too!! I personally think it will soften him up. I’m just kinda freaking out. My son I had no symptoms but this one is completely different and sick all the time.. just trying to think how to tell him if it is..
