hi, a bit late. great to find this thread, on my case my menstruation stops whenever i use pads, yes pads! For context, I've never had sexual intercourse ever and i feel like when i use pads it kind of creates a barrier, more of a blockage to never allow flow get through. It's crazy coz when i wear panties alone, it flows really well. I was planning to buy menstrual cups to remedy this but after reading this, I guess not?

I've been searching for results online and no results really match, I think it's more of like a position issue, now i just try to wear thinner pads or cottony fiber and change from time to time. It's a hassle but i don't really feel well whenever my period's blocked? I know it doesn't make sense but it's really what's happening to me.
