39 Weeks Pregnant, Where's The Braxtons Gone!!?

Hey All. I'm now into my 39th week of pregnancy and all little niggles I was having a few weeks ago have disappeared. My boy is moving around like a trooper and making things very uncomfy. A few weeks ago I was having braxtons a lot and deep burrowing pains...now I have nothing at all. I saw my midwife last week and he is head down, but with the amount of moving around he is doing in the last week I'm wondering whether he is turning. Does the baby stop moving when labour is imminent??!! I know I'm being silly but the tiredness is getting to me now x
