Has this happened to u

I'm 13 weeks n 4 days 
So I ate a small lunch today with maybe 8 munchkins(the round donut balls from Dublin donuts) then I took a nap maybe 2 hours after for about 2-3 hours n I didn't wake up hungry instead I woke up still feeling sleepy, 
It now passed dinner time but I still don't feel hungry, I served myself a bowl of cereal just so I can put food in my stomach n yet I didn't eat it all because I really didn't feel like eating anymore of it n I drank a few sips of sunny delight, now I'm back on my bed feeling sleepy n I'm feeling a lil congested (I think it's because of my allergies), is it bad that I'm not really feeling hungry even though I haven't eaten a lot of food today?
