7DPO - Hungry!

So I had 2 toast around 9am with peanut butter like I do every morning.  Then around 10:30 I started to get hungry again! like for another meal, not just a snack.  So I decided not to have anything else and wait until at least noon to eat lunch.  10 minutes later I found myself on the couch with a bag of Double Stuffed Golden Oreos.... yup eating them (only 4 though).  And I am still hungry.  I had ordered pizza last night, ate half the pizza last night and the rest was for today.  It is now almost 11am, and I am very close to eating the pizza.  I am trying not to because if I am not pregnant I have no excuse for eating so much and no excuse for my weight gain lol.
