There was an article in slate http://www.slate.com/id/2151746/?nav=tap3 that talks about new hormonal contraceptive methods, specifically birth control pills, that let a woman have zero to four periods per year. Apparently, this is controversial. I don't see it.
I have a toddler. I have not had a period in 29 months. Between being pregnant (9 months), nursing (11.5 months), and taking the progestin-only mini-pill since my son was 5 months old, menses stopped. I couldn't be happier.
The natural order of things was for a woman to spend most of her child-bearing years bearing children and nursing them. We are not meant to spend 40 years with a monthly period.
