Will the age of my first period affect my fertility?

The age of a woman’s first period won’t radically affect her fertility. A woman’s egg reserves start diminishing the moment she is born and not because of her menstrual cycle. Starting your period early doesn’t mean you run out of eggs, we run out of eggs just because we’re getting older. While women who start their period before age 11 might go through menopause a little earlier than if they’d started at 13, it’s usually only by a couple of years. And since a woman only has a one percent chance of getting pregnant naturally at 45, that means a slightly earlier menopause — 49 instead of 51 — isn’t going to dramatically affect her ability to conceive.
