Birth control question

Can you use that combination of natural hormones as contraception?

Based on what I've read: people have tried natural
progesterone as a contraceptive, and a number of pregnancies
resulted and it wasn't considered very effective. But apparently
there's a method using natural progesterone and high
amounts of melatonin (another natural hormone) which
seemed effective apparently though I saw very little
information on this.

Well, what is "VERY rare"? Obviously it's less than 1 in 100. What is it?
