Is it possible that I put the puck on incorrectly and it falls out?

Good morning is it normal that the puck is so low? Sometimes I don't feel it and sometimes when I walk it literally feels like I have a circle that decomposes It feels like it falls out. And once I have the opportunity to go to the toilet and see how low it is, it's okay to a depth of about a finger. But I have the impression that once it is to the middle of the finger and once I see its tip as it exposes the labia minora and you can see it in the entrance to the vagina. Is it a matter of habit or am I doing something wrong?
