Is it normal to feel exceptionally tired at 39 week's and wonder how on earth I can push this baby out when I do Go in to Labour. I had cramps this morning thought ok great here we go had a shower then by the time I dried my hair I fell asleep for an hour I felt so exhausted when actually I should have went for a walk to get things going. This is my second so toddler running round too. Shouldn't my body. Be full of adrenalin when Labour begins?
