U/S of Boys💙 --- is it really a boy??

So in 2016 I was blessed with my first arrival which was my baby girl and in the last few months we found out that we are expecting next year. 2018. We decided to have an elective scan done at sixteen

week where we were told that our little nugget is a baby boy. The elective scan was performed by a sonographer at an external medical facility other than my OB/GYN's office. Out of curiosity I would love to see some other scans to help ease my "well it wasn't my doctor so maybe it's not really a boy" thoughts...
