Can I have more sleep?

I start to think its my body giving me some training before baby arrival. Lately I cannot sleep more than 5 or 6 hours. Should I blame the hormonal change? So I went to bed at 10.30pm last night and I woke up at 4:30pm.trying to sleep further, but my brain was awaken already. After so many turns on the bed, I decided to wake up and happened to watch the sunrise again. 

Life is not too bad afterall!! I love summer time.
