Trying not to get my hopes up

I'm 10 DPO currently. But I have been so fatigued the last week.  I took a long nap yesterday, and multiple naps today.  I just find myself dozing off all the time.  I was really neaseaus yesterday morning, but it eventually went away.  I'm having a really hard time staying awake tonight and asked my hubby at 8:00 PM if it was acceptable to go to bed lol.  I'm due to start my period anytime between Tuesday and Thursday of this week.  I refuse to test til probably Thursday or Friday.  Luckily I have a busy week at work so my mind will be preoccupied!
