@jenn121,
um.. O.o this happens to me all the time really
My doctor says it's completely normal
I loose alot of blood sometimes, get major cramps that make me want to throw up, and i can barely breath
I am usually happy when i have my period( weird O_O)
but lately i been getting kind of moody it might be stress or something.
I never know when my period is coming, i only know the week because it changes each time, and sometimes it isn't even in the week that it is suppose to be in, once i didn't get it for a whole month or 3
and sometimes it hurts so much i can't walk
Haha it's pretty normal unless you don't eat that good watch out for the things you eat and all, that might be causing the problem
My doctor said that, that is one of my reasons why my period changes so much because of the way i eat...i don't eat very healthy lolz
Ask your doctor =D
