Question about a type of HBC(?)

[nyula.livejournal.com]

Okay VPers, I'm posting for a friend and really hoping you can help me!

Basically, my friend has been getting depo-provera for the past little while, and now he's been told that he can't take it any more, and was recommended another pill. However, he's forgotten the name of it, and all he can remember is that "it'll stop my periods but it's not a contraceptive."

I know it's vague, but I was hoping someone would know what he means? Or maybe even have a tiny little inkling about it?

Thanks in advance for all your help!
