when i emptied my cup tonight after a bath, i was surprised to find it full of what i think was bathwater! is this a sign that my cup may be too small for me? i had had problems with leaking before, but i'm relatively new to the whole menstrual cup thing, so i just assumed it was because i didn't have it in right. this is my fourth time around, and now i'm also on nuvaring, and i noticed that while the "bulk" of the period stays in the cup, i get some watery leakage. i do the swirl thing and finger check to make sure the cervix (that's what that bump is, right?) is within the cup opening perimeter, so i feel like it's in correctly, and now the only thing i can think of is that i should trade it in for the bigger size. any advice?
