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.
Hey Girls <3
It is not normal to menstruate for a month. Some causes that lead to irregular patterns of menstruation include fibroids, pelvic inflammatory disease, or polycystic ovary syndrome.
Well im not a girl but it feels like they are doing it so maybe
All female mammals menstruate in one way or another, from what I understand from a vertebrate biology class I took. Huge differences in timings, cycles and amounts though, and also causes.
The average age would be thirteen however menstruation is different for every female.
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.
yes, if you are a girl, you menstruate.
boys are different to girls but I think that the causes are similar
man dont menstruate
Thankfully, female guinea pig don't menstruate.
