"i have been on portia off and on for the past few years. my pharmacy kept telling me that levora was the same which seemed pretty true. i have no period. i thought something was wrong with me but nope, i got all checked out by a ob and the pill just causes me to not bleed which is fine by me, i do however get sore breast every month when it should be my period and i have slight mood swings. overall i think it&#039;s a good pill."
