Stretch mark rant...

I've been petite all my life, I've went through eating disorders and being 85 pounds up until age 16, to finally gaining healthy weight by 18. I'm now 20. Every since about 6 months into my pregnancy, I have gotten stretch marks all over the tops of my thighs.. Although they are the same size and not getting bigger.. I also have some on my boobs, and back.. It's just out of the norm for me. I started using all these products, and they keep getting worse and worse ! So far boring on my tummy though ! Idk if these products are just no help and were a waste of money or what:/
Anyone else the same way, where nothing you use helps?
I use coconut oil, coco butter, bio oil, Shea lotion, shea butter, cerave stretch mark cream, mustela stretch mark cream
And yes I'm aware you cannot really do too much about stretch mark
