how do you know your period is coming
a part of every girls life
Your stomach starts to ache and there is a white fluid(transparen) discharge.
add 28 in the last day of your previous period and the day which you get it will be first day of your period it is as per my study but it may vary among the girls.. before periods u will feel slight pain in your back sometimes
I get diarrhea for two days before I start..
Just when you have something really important to do or when you get invited to a swim party, that's when you'll start.
