Is it possible that instead of a pregnancy making you extremely tired it can have the opposite affect on people who generally stay tired?

I usually can keep at any time and for hours and still be tired at night. The past 2 weeks I cant sleep more then 3hrs a day. And falling asleep is a battle.

10dpo, extremely nauseous, very itchy areolas, very slight amound of cm, constant back aches and small hip/lower abdominal cramps. But I just can not sleep at all.
