Boy having ur period sucks

Naomi • N0.M3S I'm 11 and have both p's and I hate it
I know it's for having kids when ur older but I sit next to two boys at school and they always say that something smells. When I first ever got my period I thought it goes for a couple of years but then my sister told me that it goes on for forever. I almost killed my self. Why couldn't we just get our puberty and then that's how u could have kids?
