Will I know when my waters break?

With my previous pregnancies, my waters leaked during labour, I had ARM with one, and no amniotic fluid at all with Noah.
So, you might see my concern. I am more worried about my waters breaking whilst I am in the pool. Do you think I would notice? Is there a popping sensation? Do you think I will notice if it happens in the shower?

As I mentioned, I have no idea and would love to hear others experiences and feelings of when their waters broke.
TIA
