Guess the gender! Nub theory

maverick

Went today at 12 w 6 days to have a gender scan. Was told at 13 weeks they can determine gender. Was super excited to go to the appt and left without answers! Baby was super active and wouldn’t sit still. Literally jumped! Haha. The lady thought she saw something between the legs and then upon further inspection didn’t see anything. I got a good look from the bottom a few times for just a short amount of time and didn’t see anything sticking out. Still thinking it’s a girl but going back in two weeks to have another look! Adding in a pic I posted yesterday of babies nub. Read the nub theory is really reliable. From my opinion it looks like a girl nub. What do you guys think?!
