Question

what is starting age of menstrual cycle ..

Answer 1

Today, the average age to get your period sits at around 12.5 years old. This might not seem like a huge jump, but it's still a steady decline that should be noted, especially when there are girls getting their period as young as 7 or 8 – known as precocious puberty.

Answer 2

Most girls get their first period when they're around 12. But getting it any time between age 10 and 15 is OK. Every girl's body has its own schedule.
