Hi welcome to HCM
Thanks for your query
Girls first menstrual period is called menarche
. It usually starts sometime between ages 11 and 14. Menarche is a sign you are growing up and becoming a woman
. Along with starting your period, your body is changing. You've begun to develop breasts, pubic hair, and underarm hair.
In the days before you start your period, you may feel tense or emotional.
You may gain water weight and feel bloated.
You may have pain (cramps) in your abdomen, back, or legs that lasts a few hours or more
. Your breasts may be tender
