Period??.. sore ?

when you have your first period, it is always irregular, you can almost never predict your second period, when i got my first one it was the month of august (not this year), i then got my second one in the beginning of november(not this year), my 3rd one in december (still not this year), and it has been irregular for a few years now. just because you have a loooott of discharge, or many cramps does not neccesarrilly mean you can predict if it will come by next month, or tommorrow.
