I found out at 12 weeks that we are having a boy but he could only give us an 80% accuracy so we'll see if he is correct at 19 weeks.

Last year we were pregnant with twin girls but unfortunately lost them at 22 weeks due to an incompetent cervix. During their pregnancy the sonographer was nearly 100% sure with one girl at 12 weeks and 80% sure with our other girl and then confirmed their sex at 19 weeks. I guess it depends on how confident the sonographer is.
