Sleep Problems 8 DPO

I am 8 DPO and STRUGGLING to get more than six hours of sleep the past four nights. I am exhausted all day then have a hard time falling asleep at night and I’m waking hours before my alarm. This is HIGHLY unusual for me, usually I fall asleep within ten mins of turning off the lights and sleep for almost nine hours usually.

I’ve never had sleep issues before, could it be an early symptom?
