I'll be 17 weeks when I see the doctor in about a week and 3 days... I just wanted to know if she will be able to tell the sex

Usually when the ultrasound is done they can sometimes tell.
I think around 14-16 weeks so they should be able to possibly tell at 17 weeks.
sometimes/possibly=not always able to tell from the ultrasound.

I found out with my two boys at 17 weeks but with my daughter I didn't find out until 23 weeks so it depends on if the baby has it legs open well' good luck let us know

Usual around 12 weeks they can se clearly the sex of the baby or anywhere near the end of the 1st trimster because the baby is fully develop, but at 17wks they can know if they get a clear view.

I found out at exactly 17 weeks and we knew 99.9% we were having a boy, he had his legs spread open and was not shy one bit.
