It's silly. As a gardener, I see all types of reproduction cycles. Nature is so diverse that even within a species of a plant, there can be different reproduction cycles.
It looks like Mother Nature gave you a ten-year cycle. I'm sure if you had pushed it (like years of targeted sex, etc.) you could have found a shorter time span in-between. But, left naturally, your body produced one every 10.
I find it interesting that my sister produces one every two years - also like clockwork.
Then there's my friend who found herself pregnant again while still nursing. Her kids are 12 months apart. That was sure a rapid fire cycle.
Thank you for your message of support. I hope you stay with us during your pregnancy. It's so encouraging to us. I sure do hope to be joining you soon.
