Is 17 weeks far enough?

Toni

I just scheduled our gender ultrasound but I’ll be 17 weeks by then. They say if they can’t find anything then they’ll do a free follow up to try again. But I just want to know how many of you have had it at 17 weeks or even earlier and been able to 100% see the gender? I feel like I see a lot of women on here get it at 20+ weeks or do the blood test.
