i was diagnosed with V ledien factor about 5 years ago with no problems so far. when i first got my period and i had lengthy and heavy and inaccurate periods It was because of cysts on ovaries (from an ultrasound) I am now worried. i took a pregnancy test because i do fool around with my fiance so i did it just to put my mind at ease. it was negative right away. what could be the cause of it? i havent had any unchanged weight, or stress in my life. i dont over/under exercise and am average weight.
