Nub theory

[Mrs pg]

Hi ladies, how accurate is the nub theory??

Depends on gestation, 11-12 weeks is only 50/50
But late 12/13 weeks can be 90 odd percent not sure of exact numbers though

Obviously also depends if it's a good nub shot lol.
Sometimes the nub doesn't show, sometimes the baby has an arched back thus making the nub appear more angled than normal , sometimes baby is upside down which can also make nub theory harder.
My baby was upside in my shots and had very mixed responses

Mine was 100% right. Like pp said there are many reasons why it doesn't work (whole nub isn't there or to early) but 12+4 and up is pretty accurate!
