Maca powder.

It's been months now since i don't really get horny. And i feel bad for my husband he said he understands it but ofcourse i know it's not really fair for him. So i searched and read about Maca powder. I am willing to try it but is it okay to take while taking birth control pills? Most post about it here helps them get pregnant. We're not planning to get pregnant yet i just want my libido back.
