WHAT IS THIS 😭

I'm like 3 days OFF my period (ended 3 days ago) and I'm not even ovulating yet and I literally feel like a food fiend at work right now. In eating chips and ice and candy getting anxious for lunch I feel like I could eat a large amount of ANYTHING right now and idk whaaaat is going on. Not to mention I gained a good 5-7 pounds over the course of my period week, but today is the only day I feel this hungry. I'm not super mad at the weight gain, but I'm confused about this hunger I feel like a monster.
