i've been on it too for about 4 months. i dont really get my period, but i get some of the symptoms (minor bloating, minor tenderness, minor bitchiness

). last two months, i havent gotten anything and ive had sex with my fiance with no issues. i actually bled last month so i know im not preggers (woot!). im almost done with this pack, and i expect to have very light to nothing at all.
if youre that worried, call your dr and get a pregnancy test or (as a best practice), keep an EPT in your lingerie drawer to have on hand just in case.
good luck!!
