There may be nothing wrong, but have you had any other symptoms?  You may have an infection, or if you are having unprotected sex, it may be a good idea to get checked out just in case (could u be pregnant?)  Not trying to scare you, but you can never be too careful.  Stress may also be a factor.  But sometimes our cycles just fluctuate.

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.

When there's a lot of blood in the uterus, it sometimes solidifies into clots.  There's nothing wrong with you unless you pass absolutely huge clots every hour or more or you saturate pads/tampons every hour or more; if this is the case, call your doctor.  I've been there, because my cycle has never been regular and my flow has never been light LOL.

I have the same problem.  I'm 31 with 2 kids, and my periods have never been right since.  The cycle is shorter and the periods last longer.  Bummer.

I really wouldn't worry to much about it if I were you.  Sometimes that just happens.  You get lucky and have light periods.  \n\nIt could be because you are dieting and have lost a lot of weight, because changes to the body like that can cause more changes with our monthlies.  Don't worry to much and if you are worried go to the doctor and get checked out but I believe it is just a change in the body.

There could be numerous reasons for your lack of menses.\nBest thing to do is go to the gynecologist and have some tests run.\nThe problem could be something very easily fixed with a one time treatment or prescription.  Please do seek medical help.

It is not uncommon to have irregular periods. You might want to consider going on birth control to help.

Brown is usually old blood...Are you on the pill? remember every 7 years your body changes. If your really concerned call your doctor. Periods are never the same

it's not really "normal" but you're still probably ok because some people periods don't exactly fit the textbook description. try to go to the doctor and tell them about your period. it may have something to do with your hormones and they can probably regulate you periods better with birth control.\ngood luck

You need to see a gynocologist.  Your march period was way too long. You are losing too much blood.

Everybody's body is different.\n\nI went to the doctor's recently regarding period issues (I get mine more often than others) and she said that every lady is different.\n\nShe also said that stress can affect it.

How old are you? If you are not old enough to be in perio-menopause or menopause, then you should not have that long of a cycle. I think you are having a hormone imbalance and might want to go get a blood test to find out which one is lacking.\n\nThere is a broad range of "normal" among menstruating women. Unpredictable or long menstrual cycles are normal for teenagers and women in their 40s. If you are a teen, you can expect cycles to even out with time. If you are nearing the age of menopause, you can expect menstrual cycles to become longer and eventually to stop. If you are not a teen or older than 40 and your cycles are shorter or longer than 21 to 35 days, there is a chance that you have an underlying problem. \n\nAny big change in your menstrual pattern or amount of bleeding that affects your daily life requires a medical check by a health professional. This includes menstrual bleeding for three or more menstrual cycles that:\n\nLasts longer than 7 days.\nIs very heavy. If you are passing large clots or soaking a large pad per hour for 8 hours, your bleeding is considered heavy.\nOther symptoms you should have checked include:\n\nBleeding between menstrual periods. \nPelvic pain that is not linked to menstrual bleeding and lasts longer than a day.

Have you been exercising alot more than you ever have the last 3 months?\nHave you been stressed out the past 3 months?\nAre you eating right the past 3 months?\n\nIf you have been exercising alot more this might be the cause of ur period not coming this happens to alot of women who r very athletic.\n\nIf you have been stressed your period could not come. Very unlikely but it can happen.. and the same with not eating right.\n\nInstead of calling the doctor I would talk to you gynocolgist.\nThey'll no more about that than your normal doctor.\n\ngood luck :]

I agree with Heather, you should see your doctor.  I had a female friend who had "irregular" periods where she wouldn't have a period for months at a time, but when her period came it was just a normal 1 week thing.  The irregularity may be normal, but the 3 weeks of menstruation is what I would check about.
