Actually, from what I have read, having a period every month isn't good for a woman. In the past, women were either pregnant or breastfeeding most of the time, so they didn't have many periods. I've had one every month for 25 years, hundreds. And that was not at all common in the past.

I haven't been on birth control because I don't have sex with men and don't have gynecological issues. But I think a lot of women need help for heavy bleeding.
