I thought I had better attempt my birth story before it all becomes (more of) a blur :)
Tuesday (16th) night I was awake with painful regular contractions and was on the verge of getting up when they started to get less sore, then went away and I managed to get back to sleep.
Wednesday morning nothing happening so I went to my Piyo class. Wednesday afternoon was getting strong BH all afternoon, and decided to get a few things done that really needed to be done before baby!
Was very tired in the evening to had a nice bath and went to bed about 8.30. Woke up about 12.30 with what could have been strong BH but after a while I was beginning to think they were contractions.
But only during them - in between I kept thinking "only BH, must get back to sleep" 
I got up and went downstairs about 2.30. I sat on the birthing ball and went on MN. I was timing the contractions but was ignoring the fact they were less than 5 mins apart and very painful 
They got very intense very quickly and I woke dh up around 3.30 by which time I was in a lot of pain. He phoned his mum to come and look after the kids and I phoned the hospital.
After the quickest 25 miles ever we arrived at the hospital at 4.15, and asked them to start running the pool. By this time I was having 4 contractions every 10 minutes.
The midwifes faffed around with paper work when they should have been getting the gas and air ready! What a releif whn I finally got that gas and air. When they examined me I was 8cm dilated.
I didn't get in the pool til 5.10am cos they faffed about with that too - they started running it and another midwife turned it off
then the temp wasn't right. My dh said he got the feeling that they didn't really want me to have a waterbirth.
Anyway, by the time I got in the pool my contractions were very strong and I had been feeling like I could push but I think my body had been waiting til I got in the pool because 16 minutes and a couple of big pushes later ds3 was born at 5.26am on thursday 18th Nov.
The midwives (there were 3 of them standing chatting at that point) didn't even notice he was born and I scooped him out from the bottom of the pool. :)
I tried for a natural third stage but needed the injection after an hour - ds3 didn't really latch on and feed properly until not long before that so maybe if they had given me a bit longer it would have worked.
We are over the moon with ds3 - Hamish. He was 7lb 3oz which was almost a pound lighter than ds2. He is very very beautiful :)
I got out of hospital Thursday evening and did the school run Friday morning 
Sorry if that was too long!
