Think of your monthly cycle as a detailed, 4-part mission run by your body. It all starts when you hit puberty!
The Starting Line: Your cycle officially begins on the very first day of your period ( or the first day you any discolored liquids or clots) and ends the day before your next period starts.
Average Length: Most cycles are about 28 days long, but anywhere from 21 to 35 days is usually normal.
How it Happens: If the launched egg (from Ovulation) meets a sperm, they combine, and a pregnancy starts!
The Fertile Window: You can only get pregnant around Ovulation. Since sperm can live for a few days, having sex in the days leading up to and on Ovulation Day increases the chance of pregnancy.
It's common to start your period between ages 10-15. During this time, your body is still figuring things out, so mood swings and other symptoms are normal!
These are just a few things to keep in mind for your health:
Missing Milestones: If you haven't started growing body hair (like underarm or pubic hair) by age 13.
Late Start: If you haven't had your first period by age 15.
Severe pain: Whether its from back pain or cramps.
Lots of blood: If you can't get through the school day without changing your products 5 times.
If either of these things happen, it's a good idea to chat with a parent or doctor!
