Ok ladies - birth story. Wrote it all out for myself so probably a bit long winded - feel free to ignore!
8am on Saturday, waters broke. Just a trickle at first and then little gushes every time I stood up. Went to hospital to be checked by midwife at 11.30am and she confirmed that it was my waters and that if nothing had happened by tomorrow I would need to come in to start being induced.
Mum and Dad came up and took Oscar out for the afternoon so that DH and I could go for a long walk up to Wimbledon Common to try to get things moving along. Still didn?t feel like I was having contractions although my bump felt very tight and pointy.
Got home at same time as Mum, Dad and Oscar. Mum and Dad left at Oscar?s teatime to go and stay at my Aunt?s house down the road.
10 minutes after they left I felt my first contraction. Felt another one fairly shortly afterwards and got DH to put the TENS machine on. Started timing the contractions ? they were about 2.5/3 minutes apart and increasing in intensity. Called Mum and Dad to come back and contractions started coming thick and fast. Felt increasingly anxious.
Mum and Dad arrived home at 6.20pm and DH and I pegged it to Kingston Hospital in the car ? phoned midwife and told her I was coming in. Contractions coming about 1.5 minutes apart and getting more and more intense.
Arrived at hospital at about 6.35pm and had to wait for about 15 minutes in reception while they got the room ready. Seriously strong contractions now. Receptionist getting increasingly concerned that I was about to give birth there and then. She told the midwives that they had to let me in even if the floor was still wet 
and walked me down the corridor to the room (this was at about 6.55pm).
Got into room and knelt leaning against bed. After a couple of contractions put my head up and apologised to midwives for not being very sociable. Midwives laughed. Midwives were still in process of filling up birthing pool. DH persuaded them to let me get in as it was filling. Got in pool ? it was bliss. Contractions eased up a bit (think I had just gone through transition).
Felt urge to push ? midwife checked to see if any cervix left and said ?nope, there?s nothing there? to which I apparently replied ?what? No baby?? and she said ?nope, no baby, in fact you?re not even pregnant? ? ha bloody ha.
Started pushing. Felt baby moving down. Started bleeding and they couldn?t see where from so they got me out of the pool and on to the bed ? kneeling up and leaning forward over raised front of bed. After a good few pushes, a seriously stinging ring of fire and a baby whose face was going purple (they got me to push his body out even though I wasn?t having a contraction at that point) baby was born at 7.31pm. They passed him to me through my legs and Luke told me he was a little boy. Turned round and lay back with beautiful little bundle on my front. Job done. 
2nd degree tears stitched up after 3 hours (!) of waiting as registrar had an emergency c-section to deal with.
