Is this baby your first? Have a shower when your contractions start or water breaks.. phone the hospital and they can advise based on what is going on. But also trust your gut.
They told me to stay at home for first baby, but I just knew I needed to go in. I begged my mum and she gave in. 10 minutes after we got to hospital, I was rushed into theatre and he was born 15 minutes later!
I know that once my water breaks, I labour quickly. This is what I did (DS is 11 weeks now).
2am - woke up on and off with contractions
5am - started timing, but jumped in the shower and did my hair/basic makeup, put a load of washing on
7am - DH and children got up for school
7:30am - phoned hospital and they said come up whenever
8am - contractions were 5 minutes apart but the kids had no idea and I was able to get them ready for school
8:30am - hung my washing out
9:00am - left for hospital, contractions 3 minutes apart
9:20am - arrived at hospital
10:45am - was checked and she said pretty much at 4cm so taken to delivery suite. I had already informed her that once waters go, that's it. Luckily she believed me as he's my third.
12:05pm - waters broke on their own
12:32pm - DS was born
