Final Update:

I went into labour three days before the planned CS. When I went to the hospital the baby had still not engaged and I was about 5cm dialated. They rang my OB and he said he was happy for me to continue through to a VB as long as the baby had constant monitoring and they broke my waters and made sure the head engaged correctly when that happened. When they broke my waters the pain I was having increased 10 fold so I didn't really notice what was going on around me but I began to realise the room was filling with people and DH emerged from the bathroom in a white gown (I didn't even notice he left the room). They told me I had to have an emergency CS and I was in theatre in minutes and then told it would be a general as the baby needed to come out straight away. Next time I woke up I was in recovery and someone was thrusting polaroids of DH holding a baby before my eyes. I was apparently in recovery for almost three hours (according to DH) as my blood pressure was very high. I had not had a problem with it before the birth so that surprised me.

I finally met my beautiful daughter about three hours after she was born. DH explained that when my waters broke the heartrate dropped dramatically and they called for an emergency CS straight away. He wasn't allowed into theatre as it was very quick. The cord was wrapped twice around the baby's neck which was why she hadn't moved down to engage. I was very, very fortunate my waters didn't break at home as she would have been in big trouble.

In the end, despite all the drama, I don't feel very traumatised by what happened, I just feel blessed that it all worked out and my daughter is healthy (and now screaming in the background).
