With dd1 they broke at 34 weeks, she was breech so I had a ecs.

With dd2 I leaked hind waters but my waters were broken by my ob. I think I went to the hossy to early but I still had a vbac.

With Ds my waters broke at home, only just made it in time to give birth. He was technically a vbac too even though I had done it once before. The midwives didn't realise as it was all happening so fast which was fine by me no monitoring, blood work or drippy thing in my hand. Would rather it wasn't quite so fast though, it was over in an hour.
