it means that the girl is puberty
I'm not sure what you mean asking if it 'gets to them'. Most women menstruate, this is a normal occurrence so no reason for it to bother other women when you menstruate.
The factors that lead to the development of adolescence as a distinct stage of life differ for boys and girls. When boys start to produce seminal liquids and girls start to menstruate the adolescent stage is reached.
Is that even possible? Take her to a doctor immidiately.
A nine year old may get her period, but I'm not sure what you mean by sooner - sooner than what? A woman will only start to menstruate when she is due to menstruate, the menstrual cycle cannot be sped up or puberty sped-up to menstruate for the first time before you're ready.
Well im not a girl but it feels like they are doing it so maybe
The average age would be thirteen however menstruation is different for every female.
You can't menstruate while you're pregnant, that is biologically impossible. If you're pregnant and start bleeding seek medical attention.
yes, if you are a girl, you menstruate.
No, not every female gets her period. If talking exclusively of those who are biologically female there are those who don't have the anatomy to menstruate or their bodies don't produce the hormones needed to have a menstrual cycle. Pre-pubescent girls don't menstruate and women past menopause don't menstruate, also women who are pregnant won't menstruate during pregnancy (sometimes for longer if they breastfeed), and women who have a hysterectomy to remove the uterus.
The average age of menarche (first period) is 13 years old. Anything from 8 years old to 18 years old is considered normal - there are also girls who start to menstruate under the age of 8 years old, known as precocious puberty.
You can't jump-start your period.Menstruation is controlled by your menstrual cycle, a domino affect of hormonal changes between your reproductive organs and your brain. You cannot skip phases of your cycle or speed-up your cycle to make yourself menstruate before you're due to menstruate.
If by girly you mean not a tom boy, then it depends. Most girls start to get more into shopping, and texting, and makeup, and they start to get a little more flirty.
