The depo shot can really throw off your menstral system, I really don't recommend depo to ANYONE. It can have longterm harmfull side effects. I know myself from experience with the depo shot, it does different things to different people, but except to be off wack for a while, sometimes it can take 6 months to a year for your body to get back to normal from it.

You should ask your docter, is it normal not to have any periods at all?

you could be pregnant - when wuz ur last monthly period - even if is due this week or even 1 weeek or 2 - first thing is get a pregnancy test done - we have to rule that out first priority - try getting a pregnancy blood test done - u cant be too sure with home test kits - if u do want to do a home test kit then do it in the morning with ur first urine - and please do it atleast 5 times to make sure !

you can't really count on any normalcy for awhile.  There are many factors to a regular cycle.  Stress, weight gain/loss, increase in activity, extreme physical endurance, medication.  I went without a period for 14 months for no explained reason...it's puberty, girlfriend, you're in for the long haul...

You do not lose enough blood during your period for that to matter.\nYou can always ask your doctor.

You might be going through menopause.  If you aren't having any period at all that means you aren't ovulating, so I would think that you getting pregnant wouldn't be an option.  You should talk to your obgyn and ask her just to be sure - and she could probably better tell you if you are going through menopause or if you might be having some chemical imbalance that is causing you to have irregular periods.

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.

That happened to me a few months ago. Have you been really stressed out at anything lately? Stress can cause irregular periods or have you started eating anything different lately? Good luck on the doc. appt. tomorrow!

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.

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

How old are you? Irregular periods can be caused by many things including bad eathing habits...anxiety, if you weigh very little you maybe missing your perioud often, when you mean last year... when? i think you should see a doctor asap. Health problems are not a joke. something could be wrong. Also when you say you have not had sex... are you saying that there was no penetration but you played around abit? the sperm is known to survive for upto 72 hours (www.teenwire.com or 6days according to that website). My take... see a gyno immediately... this is important. and there are clinics that you can go to that are not costly. ask your friend to go with you. goodluck

Go get a pregnancy test and find out?\n\nHave you put any weight on?\n\nI had a friend who didn't have a period for 5 months because she didn't eat enough.

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.

Either your hormones haven't worked themselves out enough to regualte your period, or you may be upping your bra size a cup or two! Either way, this is natural; it's all part of puberty.

if you're not pregnant, you should go get a check up.  they will probably run some blood work and possibly put you on birth control.  its not normal to go with out your period.

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.

Stress and weight changes can cause you to skip periods every once in a while. See your doctor if you think it's something else.
