Mayflower. That's what happened to me.
Contractions every 5 minutes all day. Then they slowed down to 7 minutes. I rang them up and said pain is getting worse, but intervals are not changing. They told me to come in so they could give me something stronger than paracetamol. I went in and my contractions slowed right down. I think the longest interval was 30 minutes.
I was 3 cm dilated. They broke the rest of my waters...that got the show on the road!!!!!
Call hospital. Tell them you can't manage pain at home. Sorry to say but pain will only get worse. Let's just say, I am not sure how I would've managed the drive to the hospital when contractions sped up to 3 every ten minutes..........
