Ivy asked
What age do our bodies start making the egg (the egg for the baby)?
Soso answered
You are actually born with all the eggs you will ever have, so your body never has to make new ones.
They stay quiet inside your ovaries from before you were even born until puberty starts. Once puberty gets going, your hormones wake things up. When your body starts ovulating, an ovary releases an egg, about 2 weeks before the next period, and in the first couple of years most cycles don't have one yet.
That is a big part of why early cycles are so all over the place. For the first couple of years cycles are often uneven, usually somewhere around 20 to 45 days from the start of one period to the start of the next, and one cycle that's shorter or longer than the last isn't on its own a reason to worry. Stress can make a period late too. Tell a grown-up if your periods keep coming more than 45 days apart, 3 months go by with no period once they've started, or they keep coming less than about 3 weeks apart.
