has anyone had an ultrasound done to find out what they are having at 4 months?

i had my ultrasound at 18 weeks... so pretty close

Yes I had one done at 8 weeks and at 15 weeks. At my 15 week ultra sound is actually when we found out we were having a girl.

my dr wont tell you before 20 wks because it can be wrong

I had an early one done at 14 weeks due to possible complications. We found out it was a BOY, then confirmed at 18 weeks and again at 23 weeks.

I just had my 18 week done, I don't want to know so she just took a pic of the genitals and sealed it in an envelope. But she says she's sure what it is, we'll see! (Daddy wants to know baby's gender, not me. So now I've got this envelope sitting here staring at me until I see him.)
