Nothing. Maybe I’m just different, but nothing on my body was wrecked in any way.
I have curvier hips now, and my husband loves it. I was very skinny in HS and thought I had the body of a 10 year old boy. My breasts are a little lower than they were when I was 20, but so what? My body is still beautiful.
If I have strech marks, sagging boobies or whatever, they are a badge of my motherhood, and not to be despised or surgically removed!
I am not incontinent, nor have I lost control of my pelvic muscles. Episiotomies heal, usually with no trace (at least mine did). I am not sagging or overly stretched anywhere, and I have had two children so far.
YMMV, of course, but I love being pregnant and having babies, and I love myself and my beautiful body.
Women need to stop worrying about what terrible things might happen to the way their body looks, and start focusing on the incredible joy of what they are doing.
