this is actually really cool. ok so measure from where theres a space between ur pubic hair and belly button. put it into centimeters. then take the ruler place it under ur boob so it rest on it. see how far it goes out on the ruler than times it by the measure u got from ur pubes to ur belly button. put the breast measure also into cm also. then multiply that by ur current age and weight. then place the slashes in the right places. for example
the belly button measurement-12 cm
boobie measurement-4cm
age-11
weight-81
12x4x11x81=42704 now... 4/27/04 which is when i got my first period! pretty amazing! only works for ur first one though.

Caffeine and sugars makes these things worse if you start to have them show up, so stay away from the cokes, sweets, and junk food. Breasts also swell and can get sore as well as a feeling of bloated. Clothing feels a bit tighter and you may get headaches.
