C-section mom here

I had to have an emergency c-section with my first LO due to complications during labor. Two years later, I had a second c/s. During my second c/s I was told that my uterus was extremely thin & to wait to TTC again for 18 months. Well, we were not TTC but here I am 8w + 6d pregnant only 15 months later. I am terrified that there will be major complications due to my uterus being thin & not having the full 18 months to repair. Has anyone else been in this situation??
