So, on Monday night I felt crampy and had a bit of an upset stomach during the day. It was really low level but by about 8 DH knew something was up so I told him. I went to bed to rest and by 11-ish thought it had all calmed down but by 1.30 could see a pattern and knew that this was early stages. We called my mum to get on the first plane over to mind C and started to call/text friends to mind C until she got here.
I did sleep more during the night, on and off, and then got up around 7 and had breakfast. To complicate things, C, who is NEVER sick, sparked a temp that night and seemed really ill that morning. I went to the toilet around 8 and felt a gush so thought my waters had broken. Rang the hospital and they said that since it was a second baby, I should come in as they're unpredictable. So, we called DH's friend to come mind C and grabbed my bag and jumped in a cab. When we got there, I was admitted to the birthing centre and examined but the MW didn't think my waters had fully gone as I wasn't trickling. She told me to stay at the hospital but go for a wander, walk up and down stairs etc. and come back in 2/3 hours. After an hour and a half of this, with increasing contractions, we went back to the room because I was getting really tired. I was pretty foolish to wander around that much.
Anyway, it was now around 11.30, contractions were increasing slowly but nothing major happening. By this stage my mum was minding C so we could relax a little. They gave me some aromatherapy oils to perk me up and try and get contractions going a bit more too.
By around 1pm things had definitely increased so the mw (who I think was a supervisor) assigned a mw to stay with us. She came and examined me and said I was about 4-5cms but stretching to about 8cms during a contraction and my waters were still intact. So I got back on the ball, and next contraction, whoosh, waters went. The official record shows that E was born 27 minutes later! The MW obviously got things going a bit! Once my waters went the contractions went into overdrive, every minute and really strong. Within about 4/5 contractions after my waters breaking, I could feel the baby crowning! They were filling the pool but it's massive and takes ages and it was never going to fill on time, so I got down on the floor, on all floors leaning on a big beanbag thing and ROARED E out within about 6/7 contractions, if that, at 2.15pm. I mean, I really roared. It's kind of funny.
C was a calmer experience in the water I think. E entered the world to his mama's roars. 
So that's it! Small 2nd degree tear that's healed nicely now. It was much tougher than C's birth. I was more tired and found it much harder to focus on breathing or moving etc. later on. I was mentally stronger during my first birth.
The great part was they soon informed us that the postnatal ward was full and 'was it okay' if I stayed in the room I was in instead. Eh, YEAH!
The birthing centre at Chelsea and Westminster is new and the rooms are lovely - like a spa (check them out online). We had a double bed, DH could stay all night with us, and we had our own bathroom. DH went home around 5.30 to check on C and put him to bed and my mum jumped in a cab to come see us. I was glad she was there as I was feeling incredibly weak and light-headed, but just needed some food. I finally got dinner around 6.30 and perked up after that. DH came back and stayed the night and we got home at lunch the next day.
So that's my story!
