I had SROM with both my girls. With DD1 it took me completely by surprise. I felt and heard the pop and leaped out of bed to the ensuite floor just in time

With DD2 I had a sweep three days before she was born and had a bit of blood that day but that was to be expected. I had a tiny bit more blood loss the next day plus a bit of my plug then I lost lots of plug the following morning (the day she was born) and my waters broke early that arvo. I was vacuuming when it happened and felt fine, no pain or warning as such. Just the 'pop' and 'gush' again
