I'm 17+5, last week when I was 16+3 I had a scan due to complications in a previous pregnancy. The consultant asked whether we wanted to know the sex and confidently told us we were having a little boy. I was at the GP today for something else and when we were discussing the scan she said thAt at 16(ish) weeks baby boys and girls can look very similar and to have them check the sex again at 20 weeks.
Does anyone have any experience of this? Have you been advised the wrong gender? We really don't mind - just want a healthy baby, I was just quite surprised at what the GP had said.
