Menstrual cup

I’ve just started using a cup and I think it’s bloody brilliant! (No pun intended) No waste I don’t find it hard to put in or take out at all, the only issue I have is for some reason when it’s full and I start leaking I don’t seem to feel the leak like when I used tampons I would always feel it leaking. I don’t know if this is just me or if this is a thing?
