cup too long?

hi! I just decided to switch to menstrual cups:) I've learned that not all cups are meant for your body so I bought three :the blossom cup, the intimina lily cup one and the ziggy cup. Currently just put ine the blossom one, but the stem is kind of sticking out of me, I can feel it. Is it normal? The cup is as far as it can go, it touches my cervix, but O've not started my period yet, expecting it overnight. Do you have any menstrual cup recomendations for me? Thank you very much:)
