3 DPO Symptoms?

Actually, the TWW began a few days ago, but I always sort of disregard the first few days because I feel like no symptoms will show up anyway.

I used an OPK this month instead of charting my temps (per dr's order), so I believe I'm 3DPO.

Here are some symptoms (?):

• had to PEEL myself out of bed this morning
• woke up with a headache -- it didn't go away for about 5 hours
• oddly super tired (especially since I went to bed at 10:30p last night)
• insanely hungry
• think I'm peeing more than usual, but that could be in my head

I'll be annoying and track how I feel each DPO -- perhaps you will have similar symptoms (if that's what we can call them, even thought we have no idea if we're pregnant).
