I'm 40+3 weeks pregnant and believe I'm in early labour. I started getting contractions this morning when I woke and have been getting them all day inconsistently. However when I get up and walk about they seem to become a lot more regular/painful. Has anyone else experienced this in labour? Trying to work out when to ring the birth unit. So far contractions very from 4 - 10 minutes apart and my waters haven't broken.
