Were sneak peek GIRL results correct for you?

Allison

So I know boy results can be wrong because of contamination but I’ve always thought girl results were pretty accurate? I have 2 sons and did a sneak peek clinical test at 7 weeks 1 day with this pregnancy and got girl results!! The clinic I went to said they’ve never had wrong results before and my doctor even said she is pretty positive it’s a girl since I got girl results and not boy… but I keep hearing women actually having a boy after getting girl results. What do y’all think?
