What is the average age girls can become pregnant?

Women and girls can become pregnant once they are ovulating. It is generally assumed that the indicator of ovulation is menarche, or the start of the menstrual cycle. However, this does not mean that ovulation has occured for all women. Up to 50% do not ovulate until a year after menarche. One possible indicator is that the menstrual cycle is regular and consistent in flow.It is also possible for some people to ovulate before menarche, meaning pregnancy could occur before any menstruation has occurred.The average age of menarche is more obvious than the age of ovulation, so most studies look at this age rather than that of ovulation. These studies show that the age of menarche in societies where people are well nourished is on average about 13 and in poorer societies 15.

When will you get your peried?

I assume that you mean your period, and the first period which is known as menarche. The average age of menarche is 13 years old, but anything from 10 years old to 16 years old is considered within the normal range. Everyone is different so will reach menarche at a different age, but if you don't reach menarche by 16 years old it's a good idea to talk to your doctor to make sure everything is okay.


How do you start your period if you are 14?

Your period will start naturally when it is due to start, there's nothing that you can do to make your period start before it is due. The average age of menarche is 13 so at 14 you're not far off reaching menarche.
