Please help!

Today is the first day I'm using a menstrual cup, Diva Cup, and it's going good so far. But I get scared because the cup seems to go all the way up! I feel like I'm about to get a heart attack every time I try to touch the stem because I don't feel it unless I dig down there. Is this normal? Am I putting it wrong? I am not leaking and it feels like I have nothing inside, which is comfortable but I don't know if it's okay for the menstrual cup to go all the way up by itself. Thanks in advance! :)
