Can I say I’m just a little disappointed ?😔

I had an ultrasound this morning I’m 13 weeks and I *jokingly* asked the tech if he could tell the gender and he said not 100% but there is a theory and he could check by that... I was pretty surprised cause I know I’m pretty early and i really thought he was gunna say no and keep it moving but he checked and he’s 80% sure we’re having... a.. girl...again... I was a little excited and hopeful it was going to be a boy.. this pregnancy is so much different than my first and everybody I speak to thinks it’s going to be a boy. My symptoms sign to a boy. So I am a little disappointed 😔 I feel so bad for my baby cause I feel this way.. two girls and the third girl on the way. His and my family full of girls.. I just wanted that boy.. 😞😓
