Might be having my 3rd girl, idk how I feel

Ok so please do not judge me. If you have nothing nice to say, don't say anything at all. 
So I had a scan today. I am 16 weeks and they weren't able to see the gender. But the doctor said it looks like I MIGHT be having my 3rd little girl. I'm thrilled to be pregnant. Of course I'm going to absolutely adore my baby regardless of gender. But is it bad that I'm somewhat disappointed? This will be my last baby and I really wanted to have a son someday. I guess my emotions are just crazy. Anyone else ever experience this?
