Has anyone ever had a FALSE GIRL Sneak Peek result?!

I found out at 9 weeks that I’m having my second girl in Oct! 💕 (Took the sneak peek test at 8.5 weeks!) I was so sure I was having a boy this time but now at almost 15 weeks we’ve gotten used to the idea of having another baby girl but I just have this feeling that it could be wrong! 😬 I’ve never heard of a false girl result, just curious to see if anyone else has went through this or know someone who has! I know boy results are more likely to be wrong bc of contamination!

I don’t have my anatomy scan for another 3 weeks so I’m dying to know forsure!
