Waking up exact same time

Anyone else experiencing this???

Since around 4 and a half weeks, i'm waking up at around about (give or take 5-10 minutes) the exact same time every morning - 5:30am, urghhhh.

Doesn't matter how early or late I ate before going to bed, doesn't matter what time I go to sleep.... 5:30 im awake and im a mixture of starving nauseous and gassy :-(

I thought the early mornings were supposed to start after baby was born, not from conception! !!
