At 13 weeks they saw our baby girl was a girl! You should definitely be able to tell at 18 weeks as long as baby cooperates and let's them get a good view :) What an exciting time! Enjoy!!
Their parts are fully developed by then. .so yes, it's accurate. My dr checks gender at 16.
At 15 weeks and 5 days, my dr said girl and I gave birth to a girl. If the baby is in the right position, you'll be able to tell the sex.
i have been told they can tell accurately at 15 weeks if they can get a good enough picture.
It should my doctor said she want to wait till im 20 weeks to make sure
