Wrong gender

At 18wks I was told I was having a girl! Got the sonogram to prove it, then 2weeks later, they decided to do another ultrasound and now they say I'm having a boy.

I'm blessed with another boy( I don't have to buy much), but I had my hopes up for that little girl 😔.

Kind of want them to check again. Because what the heck was the tech looking at before?
