I would not trust it. They both have nubs at that point. And I wouldn't trust anything earlier than the anatomy scan personally. At 15weeks 6 days they were wrong for DS.
Earliest I have ever found out is 15w 3d. Even then the ultrasound tech told us not to go out and buy anything til we could confirm it on my anatomy scan at 22 weeks. She was still a girl then too.
Food for thought interesting chart
Fetal genitals start to form at 9 weeks and by the end of the 12th week have usually formed into what they are supposed to be
nub theory is pretty accurate 13 weeks and beyond
Quoting Lili's Mom HasGotitGoinOn:" So I just scheduled my ultrasound for 12w1d. My friend found out she was having a boy at hers. Anybody ever find out that early & it was accurate? Tia!"
If you're wanting any kind of idea and this is elective I'd push it back to 12 w 5d or 13 weeks and that's just for a nub guess
I had a NT scan at 12 weeks 4 days(I was also measuring out at 13 weeks 1 day) and the ultrasound tech told me it was a boy. She said she had been doing it for 27 years so she was 100% sure she was right. Then I had my anatomy scan at 20 weeks 1 day and a different u/s tech confirmed it was a boy although baby never gave us a potty shot and I don't have a pic of his parts either. I'm sure they are right with my track record but there is always the small hope they weren't and I will finally get my girl. I have to go back next Tuesday(26 weeks 2 days) for another scan since baby didn't cooperate so they didn't get to see everything. Hopefully, he won't be stubborn this time and we can see his parts. Either way, it would be nice to have the potty shot pics.

Yep, the tech who did mine said that by the 13th-14th week they are easy to distinguish, she had been doing it 20+ years..
