Shy baby...

So today I went for another ultrasound and baby was sitting down so they couldnt even take a guess on the babys sex! I went 3 weeks ago and doctor said it looked like a girl but he wasnt 100% sure because she has her legs closed... I was hoping they confirmed its a girl so I can start buying things but no! I already told everyone its a girl but after today Im not too sure... 😓😒😅
