When can they tell me the gender of my child, and BE SURE? Sometimes they're wrong ya know. I don't know if it's to early to tell sometimes or what the case is.
The Dr's wait until around 18-20 weeks for the 2nd trimester ultrasound because of other reasons. they do the scan to check vital organs and do measurements, telling the sex of the baby is just an added bonus for most ppl.
There's a private place here in Milwaukee that starts gender reveal ultrasounds at 14 weeks. I did mine at 15 and I saw it was a boy
Blood is the only way to be totally sure, but ultrasounds after 18wks are most accurate.
my first anatomy scan was at 18 weeks but I had to go back at 22 weeks to make sure.
