I was told twice that we are having a girl via SneakPeek ..

Hello, I did the SneakPeek clinical twice and it came back both times saying girl. The first time was a little over 7 weeks and the second time was a little over 8 weeks. I was so excited because this is our first girl! I went to get an ultrasound done at 10 weeks just to make sure baby is measuring as it should and everything looked great. Baby is measuring a few days ahead. But, the tech looked between the legs and clearly saw something. I’m worried that SneakPeek was wrong.. I’ll insert the picture. According to google, nothing is formed that early on. I know it could have been the umbilical cord, tailbone, etc. But, I’m still second guessing it. Thoughts??
