Serious mood swings happen to women.  Hormones fluctuate, and it effects everything from mood to how our bodies feel.  Yes, it does have to do with the women's mensrual cycle, though don't ever bring that up.  Different hormones do different things to our bodies at different times of the month.  And it gets really frustrating.  We can go from being in a good mood to wanting to cry in just a minute.  Of course, all women are different.  This effects women on different levels.  It's worse for some than others.  \nWhen a girl is going through this, remember that she can't help it.  You need to be extra nice and respectful of her, and don't make fun of her.  For most girls, don't mention PMS or anything.  We don't really want the world knowing what our bodies are doing.  Just be really nice to her, and don't take offence if it backfires.  Hope this helps!

There are hormonal conditions, such as polycystic ovarian syndrome, that will reduce or stop menstrual cycles. It's best to get something like this checked out. The doctor may want to run bloodwork to change your hormone levels. In any case, you really should get an exam to make sure you're healthy. Good luck!

Lots of women are interested in keeping track of their cycles and it is really a GOOD thing to do.. over time.  I was always taught that I was supposed to pull up my dates from years ago to current.  They show trends and stuff.. and menstrual cycle is a very important part of a woman's health history.  :)

Great apes do too. \n\n"Females of other mammalian species go through certain episodes called "estrus" or "heat" in each breeding season. During these times, ovulation occurs and females become receptive to mating, a fact advertised to males in some way. If no fertilisation takes place, the uterus reabsorbs the endometrium: no menstrual bleeding occurs. Significant differences exist between the estrus and the menstrual cycle. Some animals, such as domestic cats and dogs do produce a very short and mild menstrual flow. However, due to its small amount (and personal cleanliness in cats) it passes pet owners largely unnoticed."\n\nI couldn't find exactly WHY though.

Everyone is different. Some women do not have regular menstrual cycles. There are things that can change your cycle. For example if a woman is does not meet her nutritional needs or is anorexic she may not get a period for a while. If you are very athletic this will also change your cycle. The most important thing for you to do is to see your doctor about these concerns. Remember people will always offer advice but nobody but you and your doctor can find the correct answer to your question.

Stress can really make a woman's body react. Or sometimes if women are really active, like a runner or another fast paced sport could stop a period. Age as well. It could be nothing, but to be sure, you should see your gyno and let them know so they can do a few tests. It's better to know. Then you're stress level will go down and all will be ok :)

No darling:) Don't worry, ususally the menstral cycles doesn't become stable(as far as length between and days on) until you are in your twenties, or after your first child. your body is still growing and developing and getting used to the rush or new hormones. Many things can effect your monthly cycle.For example, your body fat percentage. If you very athletic, thin, with very low body fat you will always have a shorter more irregular period. Also if you have another feamle in your household, for some reason unknown to science. Women that live together will eventually have their menstral cycles together. Don't worry , unless you have severe cramping or bleeding,colored discharge(white or yellow), or foul odor. These are all reasons to contact your school nurse,doctor, or your parents. G'luck and be safe

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.

It is your hormones adjusting to the change in your body.  That happened to me several times. It will stop.

It's not unusual to have changes in your menstrual cycle that are unique to your body and experoience, so it is probably idiopathic and benign.  Keep your appointment with the doctor though because it there is a problem behind it, it can be VERY serious.\n\nI hope you feel better soon.
