"i am 25 yrs and have started reclipsen only a month ago. before using it i had long, painful and heavy periods (7-9 days). i do know it is early to say, but i wanted to share my experience since i was really freaked out when planning on starting it, while reading all the bad reviews. so far the only side effect is the breakthrough bleeding. it lasted for 7 days. on a plus side, my period lasted only 4 days, and only 1 day i had cramps (before reclipsen, 4 - 5 days of some sort of cramps). if the breakthrough bleeding stops happening in the next couple of months i am coming back and giving it a 10 on the rating scale. no mood changes, no pain, no weight gain so far."
