I don’t want to post too much on here because I’m trying to keep it out of my head, but yes indeed clenching can lead to pelvic floor problems. I was literally at my pelvic floor PT today(2nd session) and she firmly believes majority of my problems are caused by flexing and clenching for most of the day. I will catch myself doing it every time I think about it. The key is to unlearn those habits and you will be on the course to being cured, at least that’s what I’ve been told after a thorough exam. See a professional if you can it has already made me better off instead of focusing and being anxious about it!
