if women don't have periods, they can't have children...
Unfortunately yes, if you spend a lot of time with the person (or people) and they start their period, you may start yours soon afterwards
Most of the time people have their period when they are 11 12 or 13 maybe older. but i started when i was 11 so you will start when your body is ready. some people start when they are 9 or maybe younger.
With some people it is known in their families to not start their period until late teenage years.
about 10-12 thousand years ago
People say that if u havent had a period by the age of 18 then you should go to the doctor, people start at all different times
You can start conceiving from your first period.
That's normal. Most people get a very painful stomach pain once in a while when your period is nearing. (or other symptoms that indicate that your period is starting soon) Some people experience pain, some people not and every person can have a different time when they start getting period pains.
Your period will start within 7 days

You can start them whenever, but it is a possibility that your period will be delayed.
you start your period when you are 8-16 year old... BE PREPARED!!
It is perfectly normal to start your period weeks early and its dark brown. You mostly start with dark brown when you start your period and it turns red.
