Hungry ALL the time!

Aida • First time mom at 35. Struggled with infertility for 16 years. I gave up as I never thought it would happen. God proved me very wrong! Never lose faith.
It doesn't matter what I eat. Good or bad small or large I'm always hungry three hours after I've already eaten. Snacking only makes it worse. I'm gaining weight rapidly. Will this go away? Anyone else eating like there's no tomorrow?
