Instead Placement

This is my 2nd period trying Instead. Today it doesn't seem to want to go in quite as far, and I can't get it lodged behind my pubic bone. The box itself just says "put it completely into the vagina", and it is, but the video makes a bigger deal about getting it up behind the pubic bone. Should I leave it where it is or give up on it for today and use a tampon?

Edit: Well, I did manage to get it in place, and I used them yesterday and today, but I have discovered that it puts pressure on my urethra, making it hard for me to pee. As soon as I take it out I can pee fine. So, no more Insteads for me.
