There is not one specific answer because it happens differently to everyone
The womb holds the eggs when girls are going through puberty
Girls: get pregnant Boys: Their balls start to itch
Getting your first period is part of puberty, but happens at different ages for all girls. You probably started puberty before you got your first period and still got a way to go.
10 years old because puberty happens
The same way it happens in boys(just not in all the same areas). When you hit 12....BAM! Puberty. Girls mostly get it on the armpits.
Puberty happens to both boys and girls, as they begin to leave childhood and enter adulthood. Periods, or menstrual bleeding, happens only to girls, and is the visual indication that they're getting mature enough to become pregnant.
Its because girls have hormones. Hormones make the girls have mood swings and be emotional and annoying. This usually happens to girls that are starting puberty.
girls are sensitive because that happens during puberty and we have stronger feelings.
In boys and girls, the bodies become developed. That is the reproductive systems become mature and capable of reproduction.
That happens because the pelvic region is preparing for he upcoming baby in your womb..;)
Yes. 4chan.org is a good website for girls in puberty.
