I'm 14 almost 15, & my periods are like 5 months apart! I got my first period Feb of 6th grade. I remember it being short. Then in 7th grade I got it only two or three times during the whole year. I also remember it lasting from 1-2 days maybe 3... and really light. I mostly remember aug 2012 when I got it really heavy this was when I was just starting 8th grade. I bleed for a week. After that I never got it until feb of 2013 and it was back to the short 1-2 days and really light. Now it's June and I'm worried. I haven't gotten it in a while. I'm going to be a freshman and as I said almost 15. If this helps, I dance up to 8-15 hours a week & I'm really small. 5 feet / 90 lbs. Please help! Is all of this normal?!
