Anyone using menstrual cup? Heard it's now available here in PH. Is it safe?

I've heard about this but am not into using it. Still using napkins. They said it is washable (usually wash an reinserted in the vagina at least 2x a day as compared to changing napkins every so often) and can even be worn overnight without worrying about leakage. Regarding safety, I've read that it is made of medical-grade silicone and is hypo-allergenic. Usually, you may not be able to feel it as long as it is properly inserted.
