I so agree with abcryett
i have 3 boys,, and at our 18 weeks scan (they would not even look at the 12 week one)
The sonographer 100% identified that this little one is also a boy.
I was devastated at first, as we lost a little girl at 30 weeks, and have only had boys since.
However, I love this child so much,, and have had enough time to come to terms with it,, and "snap myself out of any sad thoughts " etc so to speak.
I know it is hard hun,, but I also take it that I am given these blessings, and have boys for a reason, so there is no point in being depressed of down etc. I know it hurts, as it still hurts me now when i see ppl mistreating their daughters,, but just know in your heart that you can give them the best possible life, and in the future,, they (as Ryn stated) will bring daughters into your life for you,, and most likely granddaughters Then you can be the best and most supportive grandma that you can be.
HTH hun,,,, chin up,, i really would wait till a later scan for a sexing to be confirmed at all.
