Why do girls get so many symptoms when they are on their period?
Because of all the hormones and things going on in your body at that time.An example is cramps. Cramps are caused by contracting muscles in the uterus.
Because its your body saying 'Heyy its that time of month girlfriend!!!'.
It's just life xD
Kinda off topic, but believe it or not men have monthly cycles as well. Obviously not all the same symptoms but it has been proven
because were cursed
just hormones thank god im a guy
Not all girls do.
