Do kegels really make a difference?

I've heard the kegels aren't necessarily beneficial. It makes sense to do them but may or may not actually make a difference. I've heard the stitches take care of regaining vaginal tightness and you'll probably tear and pee yourself before and after labor even if you do kegels religiously.  I'm almost 22 weeks and definitely have not done them religiously and although they're easy and no one knows you're doing them, I just don't feel like it. 🤷🏼‍♀️
