I'm only 36 weeks but I have a gut feeling that labour could start soon.
Yesterday I felt really tired and sick but I put it down to working too hard during the day. I haven't felt that rough in ages. Then I woke up at 4am and with out even thinking, I got up and ate a chocolate bar, almost half a packet of biscuits and a chocolate brownie before going back to bed and dreaming that Michael Jackson was annoying me by dancing in our restaurant and almost setting fire to it.

Nothing usually can make me get out of bed at night. I hardly even have to get up to pee!!
Again I don't know if it was maybe caused by low blood sugar as I was shaking a bit while I was eating.
Then today I got up feeling really tired and slept on the sofa till I had to go to the doctors. He said LO is head down but not engaged yet. When I got home I slept on the sofa again for a few hours & still felt really tired after. I could easily go back to sleep now. This afternoon I've had diarrohea a bit too (sorry TMI). I've had Braxton hicks but nothing unusual or strong and I just feel generally rough but I don't think I'm ill. LO has hardly moved much today either which is quite unusual for him.
