What happens before your very first period?

Up to two weeks before your first period, this may happen.1. You may get cramps in your lower abdomen-your uterus mucsles are hard at work2. You might start feeling crabby or sad-this is controlled by hormones3. You probably will notice small amounts of white-ish discharge in your underpants-this comes from the vaginaIn the days leading up to your period, this may happen.1. The discharge will get heavier and maybe more sticky2. You will likely get worse cramps3. You will cry easily or loose your temper over nothingHope I could help!~Maggie age 11.
