Yes, you can. There are many women using both and we don’t hear any complaints at all. However we are aware of cases in which the device was pushed out. This can happen with the lower cervix or inserting a cup too deep. The spontaneous push out is a case of one in twenty devices, most common in three weeks after the application. If this is your case, we recommend asking our gynecologists to shorten the threads as possible and rely on your pelvic floor muscles when removing the cup. Most of the women however happily use both at the same time.
