Mom tummys

Let me start by saying that I think mom bods are gorgeous, but i just wanna know does every moms stomach have loose skin and the belly button that looks farther in, if that makes sense? Has anyone been able to have a completely flat stomach after baby? I was thin before I got pregnant and I’m only 5 weeks 6 days now and my stomach is giant because of bloating/constipation and I really want know if I’ll be able to get back to how I looked before. I wasn’t fit or anything just small and I didn’t work out. Opinions? Thanks
