I could tell, but why don't you ask your Dr., if your old enough!!!  I wouldn't want to get in trouble by anyone's parents!

You can buy an ovulation kit in just about any grocery store that can tell you when your are ovulating.....

you should ask your mom or if you have a older lady or sister ask them, even a  teacher or nurse would be able to talk to you.  Anyway, any where from 9 yrs old and up depending on your hormones.  You should ask an older trusting relative or close friend, teacher or nurse, that's the way to go and get the right answer for you.  Don't be afraid to ask, it's ok.

FYI,....Count however long, in days, it is from the 1st day  of one period cycle to the 1st day  of the next. Usually 3 months or more of this observation (mark it on a calendar) will give you a good idea of your cycle length.   Take that number and divide it in half.  For instance,  if it usually about  26 days from the start of one period to the start of the next, then half is 13.  Then day 13  of your cycle is about when your ovulation occurs (releasing of an egg) and when you can become pregnant. Allow 2-3 days before your half-number and 2-3 days after it to encompass the whole ovulation time. Usually ovulation last just about 3-4 days.  This is for a fairly normal-cycled female. If your periods are very inconsistent,  then DON'T count on this.  See your Dr, anyway, about it, for more personal exams and directives.
