Have you been sexually active? Then the answer is YES you could be pregnant!

You may have just skipped October, it happens. See what happens when your period is due this month. If still no period, try another test or see your doctor, health clinic, school clinic, or planned parenthood for a pregnancy test at one of those locations.
If still negative and still no period, your doctor may or may not want to do some other testing, but it is not unusual for periods to become irregular once in awhile for many teens. Obviously being sexual active, pregnancy will always have to be a possibility to check for.
