Anatomy Scan Update

Went in for my anatomy scan today and didn't go as planned I had a early scan at 17 weeks showed that I was having a boy today it looked like a girl then it looked like a boy and it went back in forth between both the whole time said it's possible that it could be the placenta and my baby was very active he/she kicked and moved the whole time I'm just going to buy unisex clothes the be on the safe side
