Anyone taken Sneak Peek at 7.5 weeks and had an accurate girl result?

I took my Sneak Peek test at 8 weeks on the dot based on my LMP. Went in for my first ultrasound and they had my due date as 4 days later. Granted that date isn’t actually possible unless my husband has super sperm that can live for over a week but it’s hard to argue with doctors. So based on the due date they gave me, I took it too early. We already have 2 boys and I’m going to be heartbroken if this girl is actually a boy 😔
