Hello, I am new here :) stumbled across it in my frantic search for nub insight.
I got these pictures at 13 weeks. Firstly I'm not certain they are nubs. One of them seems more likely than the other. But also I keep going back and forward on it - it seems to be in the grey zone. If anyone has any confidence in guessing I would very much appreciate it!
