YOUR ON SOME KIND OF BIRTH CONTROL PILL BUT YOUR QUESTION IS A LITTLE VAGUE.... IF YOUR WORRIED CAUSE YOU HAVE NT STARTED YOUR PERIOD, I DIDN'T START TILL I WAS 16 SO SOME PEOPLE NEED A LITTLE MORE TIME!

That could happen up to a week before your about to get your period. . is it coming soon? Mine just recently started to hurt about a week before i start and I'm 19. It never happened before so it's possible this could be the reason....\nIt's also possible they are growing?!?!?!

There are lots of things that can cause you to miss a period.  Stress, weight gain, weight loss, illness, or  hormonal irregularities.  You should go see your doc, you may need to be given something to jumpstart your period again.  And don't worry!  I once went 8 months without a period and to be honest, it was a GREAT 8 months!

No, it's not unusual for girls your age to not start their periods. Some girls just don't start it till later.  Sometimes a late start can be genetic.  Did your mom or anyone else in your family start "late" as well?\n\nIf you really are concerned about it, talk to your parents and school nurse.  It could be that something might be wrong, but it's unlikely.\n\nBeing boy crazy isn't exactly a bad thing, and not every girl becomes boy crazy at the same time, if they become boy crazy at all.  Lots of young girls and women like boys and men, but they don't lose their heads over them.  It really depends on your personality.  Do you go crazy for other things?  If not, it may not be in your personality to go crazy for them, but just like them instead.

START TAKING BIRTH CONTROL. THAT HAPPEN TO ME AND I NEVER KNEW WHEN MY PERIOD WAS GOING TO START AND I DIDN'T LIKE NOT KNOWING WHEN I WAS GOING TO START BLEEDING. BIRTH CONTROL TELLS ME THE EXACT DAY I WILL START AND IT DOES EVERY TIME.

It can start as early as 8 years old, but that's very rare.  If it doesn't start by the time a girl is 16, she needs to see a doctor.  It continues until menopause, which causes the woman to stop getting her periods and can occur in her 40s or 50s.  It's extremely rare for menopause to happen in a womans 30s, but not impossible.\n\nYou're more likely to menstruate on about the same schedule as your mother.  Starting at around the same age (maybe a little earlier), going through menopause at around the same age, with a period that is like hers in terms of how often it happens, how long it lasts, how heavy it is, and whether you get cramps or other symptoms.

My cousin did not get her period until she was 15. It can be a good thing too. Your growth is stunted by menarche. You say that you are a tom-boy? I am guessing that you may play sports with the boys? Being very active rather than towards the always-in-the-house, near-overwt girl, ...will prevent early menarche. I got my period when I was 10.5, but I over-ate for my size...and I was soooo inactive. You are most likely  normal. Don't fret just because most of your friends/peers have their periods already.

It's just genetic, and also related to body-fat. (Very thin girls often start later).\n\n15 is still totally normal. Lots of girls don't get a period until they're 15 or 16 and there's nothing wrong with them.

Most doctors agree that if you haven't started menstruating by 16 it could be indicative of a problem, like hormones or thyroid issues. Also, if you have an eating disorder or are extremely athletic, or are under a lot of stress you will not cycle. It DOES NOT mean you can't get pregnant. See your Gyn so they can find the issue- and yes, unexpelled endometrial lining can have negative effects. See your doctor soon, but don't freak out- it's common.

You may just have an irregular cycle. Periods can be erratic when you're in your teens. If your doctor finds that that is the case, he or she can prescribe hormonal birth control to keep your periods regular.\n\nI'd suggest going to a doctor, but you seem to have that base covered. Good luck. :)

it varies - depends mostly on how quickly your body matures.  Some have their period as young as 10 and others don't get one until they are sixteen or seventeen.

Talk to your doctor. This is not uncommon in some girls. My sister only got her period every 3 months and then had to go on birth control to make it regular. Definately go to the doctor.

Can you be a bit more clear... why did the doctor think you would start over the summer?  Unless they were giving you meds to start up your cycles, there's no good way to predict the onset of menstruation.\n\nAnyway... it's normal for your first period to happen as late as 17 and a half, and even after that, it doesn't mean you are unhealthy, just delayed.  If you want, you can go back to the doctor and ask them about hormonal treatments (typically the pill) to get your cycles going, but it's really not necessary.  If you are worrying about your period starting in school, carry a couple of pads in your backpack (your school nurse will also stock them).  Women having horror-story first periods and bleeding through their pants or whatever are very rare.  Your period is actually not that big of a deal, and will quickly become routine.

Well, how old are you? If you've never had sex and you're still young, it's probably just your period starting up slowly.\n\nIf you're an adult and are sexually active, that's just gross.
