Will I ever have a flat tummy again?

Hello everyone I am a 21 year old new mom who had an unplanned C-section. I am now seven weeks, postpartum and feeling very hopeless. My pre-pregnancy weight was 117 I didn’t gain 70 pounds being pregnant. I’m down 20 pounds now, I’ve lost a lot of weight since birth but my stomach hangs now because of the C-section I plan on losing a lot more weight by exercising (walking running some light core workouts) but do you think that will be enough? Is this my new normal and will the pooch ever go away? Please let me hear your success stories I would really appreciate the encouragement and any advice is welcome as well, thank you
