Early gender GONE WRONG???!!!!!

Chrissi • Due date July 21, 2016 with a baby girl!!!! 💓💕💞🎀 Due again August 21, 2017 🎉🎊🎏
Hello ladies! Currently 17w1d and had a gender determination done (electively) when I was 14 weeks and we found out we're having a girl. I saw clear as day that the baby had three little lines and it was very flat in that area. I am having an anatomy scan done in about two weeks but was wondering if any other mommies had an early scan done and the prediction was wrong?! I'm not really concerned because like I said the picture was surprisingly very clear but there's always that thought in my head like " what if the scan was wrong? " let me know ladies ! 😘
