I didn't find out with my first 2. Not for not wanting too, they just couldn't see. I HAD to find out with my 3rd bub, I already had 2 boys and deperately wanted a girl.I had another boy, but finding out early helped me I think. I also found out with my 4th bub, a little girl. Don't think bub's sex is going to change if you find out durig the scan sweety

Goodluck and I'm sure whatever you do, you will be happy.
