So here is my birth story.
Woke up at about 2am with abdominal pains. Thought it wss the chinese curry from the previous night. Got up about 2.30 went to the loo and sure enough a little bit of diarrohea. However cramping didn't stop, in fact got worse.
At this point thought may be labour but really thought just bowel problems! Cramps were fast and running into each other. Got off the toilet and started walking around a bit. Cramps were more like contractions at this point. But there wasn't much rest between them so I still wasn't sure.
Anyway they were very painful so thought whatever bet wake DH and go to the hospital. Woke him and he took one look at me and said we'll go now. I started faffing about getting changed, whilst doubled over in pain 
. He basically told to stop being daft and get in the car.
This was about 3.45am by then.
So had a contraction at the top of the stairs and then one outside front door and then one by the time we got the end of the road!
DH bless him drove like the wind although he did think I was overreacting when I said I need to push and Oh there are my waters gone. So he passed me his phone and I rang the delivery suite who between contractions said they'd meet me at the door.
A few jumped red lights later got to the hospital. Got out of the car midwives there with wheelchair asking me how I'd like to sit int it. I said baby is coming now. One push head was out next push baby out. It was like you see in the soaps! They rushed baby inside into the warmth and all I heard was DH saying oh we've got a baby boy! Placenta delivered inside a few mins later.
2nd degree tearing and some very painful after birth pains which tbh was worse than the labour! Baby been monitored for last 24hrs for blood glucose - all fine. Just a few issues breat feeding - v. painful.
Altogether a lot easier than DS1 and feeling much fitter 24hrs later.
