I don't EVER feel hungry! Is that normal!

I honestly NEVER feel hungry. I don't know if it's because I'm 25 weeks and the babies are squishing my stomach so much that I don't feel hungry at all or what else it could be. Does anyone else feel like this? Along with my regular groceries, I bought junk food today hoping to temp myself to eat more, but even the Oreos, Eggo Waffles, and Ice cream I bought today don't sound good to me. Is this normal when you are carrying twins?
