When you have the cup inside, you shouldn't feel it and you shouldn't feel any pain. Carefully take the cup out and reinsert it. Unlike regular cups, the Beppy Cup is inserted deeper, near the cervix.
When you experience discomfort or pain when inserting the cup, it is possible it opened too quickly. Before it has reached the right position. Keep the cup squeezed together as long as possible and let go when you have inserted the cup as deeply as possible.
