"i have been on (or was on) orsythia for about two years. i took a break from it to try the nexplanon implant, but came back after a few months. the first time being on it was so-so. my first period on it lasted about 3 weeks. after stopping and being on it again, they lasted a normal amount of time. this birth control never did anything to lighten my period, but it did help regulate it and my cramps stopped. i also never experienced any of the bad side effects that the other people leaving reviews have. however, i have not ever taken it late, nor have i missed a day, and i still ended up pregnant. i still give it 5 stars because of the positive experience i had with it before i got pregnant, but i guess it does happen."
