Boy or a girl?!

El

I was 13 weeks pregnant when I did the sneak peek test and it came back as a boy. We even took the test in the lab to make sure no contamination ( washed my hands but didn’t scrub my nails). At 15 weeks baby had it’s legs crossed so couldn’t really tell and we had a gender reveal for a boy. Well here we are at 18 weeks anatomy scan and they are saying it’s a girl!! What do I make of this?! There was a 1% chance of the dna blood test being wrong due to contamination but still?! What do y’all think?!

Thanks!
