Anyone else do Sneak Peek gender test??

Lauren • Jersey Mama to Faith 💖 Asher 💙 and Hudson 💙

I just sent my sneak peek gender test blood sample back, awaiting the results! I'm so nervous about possible contamination since I have a son. I've been feeling like this baby is a girl but I don't know if I'll trust the results if it comes back boy because of the possibility of contamination! Has anyone else done this? We're your results correct?
