Although there are no exact statistics, the chance of your belly button popping out is actually quite random.
Some women experience it while others don’t.
Most women who experience a belly button popping out find it happens around 20 weeks gestation, although it can happen earlier or later.
There’s no reason your belly button has to pop; in fact some women find that having a belly button that pops out can be painful, as it rubs against their clothes, which can make it red and chafed.
This is one of the reasons that some women put tape over their belly button during pregnancy.
