Why haven't my period started?

I'm not sure if this will help you, but my cousin's oldest daughter has this same problem.  SHe is 14, though, and is being seen by specialists at a special hospital.  She is 3 feet tall.  It is her thyroid and they are trying experimental medication on her.  She may have grown an inch in the last year, which is great.  I also have small hands, but not smaller than average.  I would take the advice and get your thyroid tested.  Then again, due to that hormone missing, that may be the reason behind it.  Is it Estrogen?

Are you sexually active? If so you could be pregnant. But my guess is your not, so you should talk to you mom and go see your gyno.   Has it been more than a month because periods are sometimes irregular.

I am assumeing your a young girl so maybe your period is just not regulated yet stop worrying about it and since you said you didnt have sex maybe it will come on its own.

You're young, and just starting to menstruate. Your body isn't on a regular cycle yet. Don't be alarmed. Cramps and light spotting are very normal. It may take up to a year before your periods regulate themselves.

Hello, I got my period on my 16th birthday, and I was skinny and athletic just like you. The reason why you are not having your period yet is probably because you are so athletic and skinny and also don't get nervous or stressed to much; it might delay your period. Just relax and nature will take its course. I hope this helps you.

Periods can fluctuate.  You can also trick yourself into thinking that your pregnant. \n\nDon't worry.  Sometimes your body doesn't take as long for a period as it does on other times.  If you've had some really stressful stuff happen, your body might have cut it short.  \n\nSometimes, when you're consistently having really short or too frequent periods, you're not ovulating.  If you keep having problems talk with your doctor.\n\nHe can give you a prescription for a few days worth of progesterone to jump start your uterus and get it back on track and more regular.  But only bother doing that if you consistently have problems with your period.

Your age plays a big factor.  Could be stress, diet, over exercising, weight, or even a medical condition such as fibroid tumors (which is what I had). Don't worry too much about it unless you skip two months...... \nBy the way...how you do definitely know that you are not pregnant?

You should muster up the strength to take a pregnancy test.   And yes, you should see a doctor.  Even if you're not pregnant, there has to be a reason that you're not having a period.\n\nGood luck to you and I hope you've got a little bean.

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!

Not likely.  The most common causes of missing a period are stress, too much exercise/dieting, and being pregnant.\n\nAre you smoking quite a bit extra because you're stressed out?  Maybe the one thing is obstructing the other.

You need to see a gynocologist about this problem. there can be many reason why you're not having normal periods. Reproductive endocrinologists as well- they're highly specialized and can tell whats going on if you're having a hormone problem, which is likely

There are several reasons that could be causing a delay in your period. Some are more serious than others, and there are factors that have to be determined, like how often does this happen and how many months you go without getting your perdiod, you might not even be ovulating. The best thing you could do is see a doctor, that way you will know if it is just transitory, have test done, and if necesary, you can recieve treatment.

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.

Yes. Periods change from time to time due to alot of different things. I would suggest that you wait a week or so and if it still doesn't happen, get a pregnancy test.

Don't worry.  Every girl is different.  Your body isn't ready yet and that is normal.  Enjoy not having a period yet because they really suck for most girls.  My daughter is 12 and she spotted once when she was 11 and then nothing since.  That can happen too.  Normal.  Most girls don't get their period and have a regular 28 day cycle from the beginning.  I've known lots of girls that don't get their period until they are in their mid to late teens.  It's not as common as those of us that start early on (I was 11) but it's not abnormal or anything to stress about. :)

There can be alot of reasons a woman misses her period. She could be pregnant. If you are very athletic you may have fewer periods each year. Also if you are malnourished you may not have a period. Those are just a few reasons. You may want to consult your doc on this one.

there is nothing you can do to make your period start. you really need to see a doctor who can thoroughly assess you and work out the reasons you are 18 and not had a period. As you are in fact 18, you are an adult, so take yourself to the hospital or doctors and get a professional opinion.
