My waters went around midnight, and I've been into hospital. They sent me home to wait for labour to start. It did and I was having contractions every 2.5-4 min which were 30-40s in length. However, it seems to have slowed right down now, more sporadic and weaker:shorter contractions. I'm tired after being up all night- should I take the opportunity to slew a bit or stay active to try and ramp things up again?
