Tampons 🙄 a lil TMI

So i was finally able to get it in there (AFTER THE 100th TIME). Ive been wanting to wear them because since I have dance, wearing pads can be SUPER uncomfortable. But anyways everything was fine for the first few seconds until I started feeling the bottom of the tampon kind of... slipping maybe?? I don't know if that's just my head or maybe I didn't insert it deep enough...?

Any advise on how to make sure it really stays in there for good would be greatly appreciated!!
