I would go talk to your doctor. There are a couple things that it could be.......one is Polycystic Ovarian syndrome, the other is a hormonal imbalance. I suggest you go and get some bloodwork done from your doctor, and they will help you find out what's wrong..... :) there's no need to worry, they might put you on birthcontrol (if you're not already on it) or they might try something else :) hope this helps

Well you skipped just one period. That happens to me sometimes, but I just got mine like two years ago. It usually happens when I am very active or something. So maybe your body just shifted its timing  or something. but if it worries you, just see a doctor.

It has nothing to do with your period. I assume you are still young. At your age your period will not be completely regular yet. For a lot of woman their period will never be completely regular. Don't worry about it.

Definitely tell your mom. after all she's a woman, if not anything else. She'll surely be able to tell you. probably its a genetic trait, to get delayed periods. Armed with all this info, U and your mom cud see the GYN y u'v not had your periods. \n\nDon worry. I got my periods wen i was nearly 16. an my mom was hell worried till then.. iv had problems with it after that too, but nothing which was not solvable. \n\nSo chill. Have faith in the Lord as well. \n\nTake care and lemme know. K?

Are you breastfeeding?  If so, you won't get your period until ater you stop.  Even if not, sometimes the body needs a few months to get back to normal.\nHowever, if you do not get your period that does not mean that you cannot conceive.  But it also does not mean you are pregnant.

Yes, you could be.  You could also be exhibiting false symptoms if you're at all anxious about it.  This could also cause your period to be late.  Don't jump to conclusions yet; give it a another couple of weeks.

Congratulations!  No, you definitely do not have to worry. It's annoying when your period shows up unexpectedly like that, but not everyone has an ultra-predictable cycle, especially when they're really young.  It might take a while for your body to establish a schedule, but that alone is not something to worry about.

How old are you?  It's very normal for your period to be irregular in the first few years...it can take up to five years to even out, though you should see a doctor if you're still irregular after two years or so.\n\nHowever, it sounds to me like you are indeed pretty regular - just not on the typical 28-day cycle.  Every person is different, and a period is considered normal as long as it happens every 40 days or less...so don't worry too much.  It's also normal for it to only last three days.\n\nIf you're really concerned, go see a doctor.  It will make you feel much better.

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.

The normal time to start having a period is between 10 and 16.  It's ok if you don't have one yet and your friends do.  Don't worry, it will happen for you.  And don't try to rush it.  Once it happens, you will understand why I've said that.  I personally started at 8 (which is VERY early), but my mother and my sisters all started at 15 or 16.  It's normal.  I'm not sure how old you are.  But as long as you are under about 16, it's ok if it hasn't happend for you yet.  Talk to your mother (if that's possible for you) and find out how old she was.  This will help you better understand what is happening and when it will happen for you.

You're still in your teens, and women's cycles don't become truly regular until the mid-twenties. Your body may have just randomly skipped a cycle. Rapid weight loss or malnutrition can also cause a missed period. As you said, stress can do it too. Also, some illnesses (ovarian cysts or uterine cancer, for example) can do the same. That's a very unlikely possibility though.\n\nIf you're sexually active, take a home pregnancy test once your period is a few days late. If it's negative or you're not sexually active, wait another month to see if our period returns. If it doesn't, head to the gynecologist for a check-up.

Hormones vary with periods of stress in life. Infections also may cause a lack of a period. An anovulatory period is most likely what your having, they are vary common when your young. It just a time in life when your periods will be off. If your not active, it should correct by the next month. Doctors don't usually worry until three consequtively missed periods.\n\nOther than that, alot also has to do with your weight, and familial history. But when your young, your hormones are crazy. So sometimes two cycles in a month, sometimes none.

When you are in your teenage years, your period is going to be irregular, especially if you haven't had it for that long.  But if you go several months without having there could possibly be aproblem and you should see a doctor.

If you are sexually active, try to get pregnancy test or go to doctor. \nIf you are not, then you might have polycystic ovary syndrome (PCOS) where women lacks mentrual flow, tend to be overweight, stress, etc. \n\nBest go to your doctor and have tests run on you and let the doctor tells you what's the issues.

This happens to lots of ladies, and if you have not had sex, then you are NOT pregnant.  It's just irregular periods, and it is most common when you are young and have only recently started having periods.  Don't worry about it for now.  If you get married and want to start a family, and this is still happening, then you might want to ask your doctor to check things out to make sure you are going to be able to have children without taking extra meds.  \n\nI♥♫→mia☼☺†
