You will be able to see the gender at 19 weeks. I think after 15 weeks they can determine gender pretty accuratly. My OB won't let me go in sooner than 20 weeks. She wants to make sure that the baby is developed to 20 weeks so that they get proper results for the measurments and scans of the heart, vessels, brain, etc.
Re: also who had luck on seeing their baby's gender on week 19? should i wait til week 20 or 21?
my read shelf:
We did an elective u/s at almost 16 weeks. The sex they predicted was confirmed at our 19.5 week anatomy scan.
Obviously, we have yet to confirm for sure. But two different places (elective place and doctor's office) agreed with each other.
We found out the sex at 16w3d (confirm at 2 later ultrasound as well). The tech said it was very clear to her.
You should definitely be fine at 19 weeks.
