Will my body ever look remotely similar again?

I was 110-115 lbs pre pregnancy and at my lowest 103, I am now 37 weeks and weigh around 150. I'm 5'1
I think I'm most insecure about my legs and butt- covered in cellulite and stretchmarks. My legs and butt used to be somewhat toned and smooth and only had a few spots of cellulite. My back also has rolls of fat now which I've never had before. Even my face is chubbier.  I know stretch marks will somewhat fade, but does the cellulite go away? To what extent does your body return to normal? I will exercise as soon as my doctor clears me to after birth, and I've kept fairly active this pregnancy but it just has not been kind to me. I know my baby is worth it. Just scared I'll never have my self confidence back.
