@Ella it goes from bladder to nub middle or top , be used the boys is stacked it gives over 30° which is not. Labia lays parallel . There are confirmed babies
But if you can see the labia, you don't need to guess with nub theory
You misunderstanding. Nub is early genitals. Nub that is developing to labia is flat - 2 lines, nub that is going to develop to a penis is one line and a dot or two angled lines . These are still nubs those babies above are only 12 weeks +
Those bladders are in identical positions. You could draw a different line and call it parallel to spine. Makes no sense.
