Menstruation

Your legs hurt during menstruation due to menstrual cramps. The same hormones responsible for causing uterine contractions can also effect other muscles within your body, pain also tends to radiate.

That is new blood and it comes from your uterus where the lining of the uterus has been shed to make room for another one. It's a like a sore bleeding so it's normal.

It's neither good nor bad to drink cranberry juice during your period or any other time of your cycle. You can drink what you like when you like, there's no benefit to cranberry juice during your period.

There are no foods that you shouldn't eat during your period, you can eat whatever you would eat normally. Unless you notice specific problems with certain foods then there's no reason to limit what you eat.

When a girl reached menarche doesn't really reflect when she will stop growing or developing. Most girls will stop growing in height by around 16-18 years old, development occurs into the early twenties as fat distribution changes to change the shape of the body. But everyone is different so everyone develops differently.

I don't have an answer but I have the same question.

As long as you're not sexually active and have recently started to have periods it is not uncommon for them to be irregular. If you're worried talk to your mum or gp

I'm assuming you've never had a period before. There's no real way of knowing until it s sneaks up and ruins your underwear the first time. Don't worry they are rarely heavy enough the first time to ruin anything else.

yes

Nothing. You can't start your period. The body decides when you start. It is a combination of hormones and DNA. Be patient it will start soon enough and you will have it for 40+ years.

When you're on birth control, that small amount of blood counts as a period. If you are at risk for sexually transmissible infections, then get screened at your health care provider.

No. It stops when it stops.

It means that you have an irregular cycle.

In order to hve a regular period you have to have a regular menstrual cycle, for you to ovulate on a regular basis, if you're young this can take time to happen as it takes your body time to mature to a point where it will ovulate regularly. If you have poor health or are not a healthy weight this can effect ovulation too, thus can cause irregular cycles. If concerned talk to your doctor to figure out why your cycles are irregular and look into treatment.

Yes, of course you can lay on your back while on your period. You can lay in whatever position you find comefortable, just make sure you're using correct protection such as a long menstrual pads or a menstrual cup to avoid blood leaking down between your buttocks and getting onto clothing or bedding.

After a woman enters puberty, her cycle begins. At the end of the cycle (which is plus of minus 28 days) the bloody inner lining of the uterus breaks down when the egg was not fertilized. The liquification of that bloody lining is what is expelled at the end of the cycle (period). The uterus contracts to help the bloody lining expel. The uterine contractions are what cause the feeling of cramps.

If you are bleeding after having a urinary tract infection and your period is no where by near due, go to the doctor ASAP! Your infection may not have been treated properly and be causing you extreme damage .

This is normal after using the morning after pill. The emergency contraception works primarily by either preventing ovulation or can also cause uterine lining to shed early. As it stops or delays ovulation then it can stop or delay menstruation, and it can take around three months for your body to adjust to get back into a regular cycle.

Timing is a genetic thing. Also soy milk at a young age can cause early puberty.

No, a yeast infection can't be cured by menstruation.

If anything a yeast infection may be made worse by menstruation because during menstruation the blood changes the pH of the vagina so it is more favourable to harmful bacteria and yeast. Using certain menstrual products such as tampons or commercial pads can also increase risks of infection, commercial pads especially can cause yeast infections as they prevent air-flow to the genitals so making the area warm and wet so perfect for yeast growth.

If you have a yeast infection it's best to seek treatment, confirm diagnosis with a doctor ideally (especially if you're sexually active, in case it's something else), and then you can use over-the-counter yeast infection treatment.

How many years a woman menstruates for depends on when she reaches menarche, when she reaches menopause, how often she is pregnant, whether she suppresses her menstrual cycles with hormonal birth control, if she has any health problems that prevents menstruation, and if she has a hysterectomy. On average women will menstruate from 13 years old to 55 years old.

Yes

Its typically because it is old blood. It is less and less common as you start having more periods

It depends on what you mean by 'clean blood' during your period. Your menstrual flow isn't dirty so your blood should always be 'clean' during menstruation.

It varies from woman to woman; but the cycle is normally 27 - 32 days long. The period itself is normally 2 - 4 days.

Stress, diet, other hormone imbalances and pregnancy.
