Just wondered as I am 39 weeks tommorrow and the midwife said the head is still free. Have been merrily boinging on my birthing ball and am currently sitting cowboy style on my office chair! I have noticed since yesterday that when I wee, it doesn't come out very well! (sorry tmi!) Is this a sign maybe? I am sure lo is more down on some days than others aswell, so is it possible for them to engage and dis-engage? (This is baby no2 btw.) TIA
