Eeeeek, I had to post!
I’m 40+4 and woke up at 4am feeling fairly damp and realised my waters had gone! Started with mild contractions not long after I waddled to the loo to check I hadn’t just wet myself! 
Called the birth centre and they told me to come in to be monitored. They confirmed my waters had gone and monitored babies heart rate. All was good so they sent me home.
Currently happily bouncing away on my ball, waiting for more to happen!
So excited to meet our baby girl!
