The most dramatic change for girls is getting their period - the monthly shedding of the uterus lining, experienced as bloog trickling from the vagina. The period is the result of a roughly four-week cycle in which the uterus lining builds up with blood and an egg matures in the ovary and travels down into the uterus. As long as it remains unfertilized, the egg will drop away along with the blood from the uterus's lining after about two weeks.
Periods are driven by the monthly release of an egg by the ovary into the fallopian tube.When do the Puberty Periods start?
Periods usually start around the age of 13 or 14, but many girls start them earlier or later. Each period lasts three to five days. although it is not unusual to have longer or shorter ones. It can take a while before periods become regular.
Having a period can hurt a lot, a little or not at all. A "cramping" feeling in the stomach can be eased by applied warmth or taking a mild painkiller. For most of us, the discomfort is less of an issue than feeling confident about managing our periods.
Tampons, used with or without an applicator allow activities such as swimming. However, some of us are more comfortable using pads.I have personally heard some young girls say, "I felt awful. I could not even image how to go home because of the pain. I went to the school nurse and she gave me a couple of painkillers and a hot drink. I laid down with a hot water bottle and I soon felt better and got back to class." So, yeah it may help you too ;)
