Are periods necessary?

I heard back in ancient times women didn't have periods like that. When they did it wasn't as heavy as your average woman today.

Yes

Technically you don't, but it makes me feel uncomfortable to go without it for very long. Like 4 months max. But that's because I worry about getting pregnant and not knowing.
