"i was on this pill since the end of april, and everything has gone downhill since then. i bled for 21 days straight, then the bleeding stopped for about two weeks. after that, i bled everyday for the remaining two months, up until the sugar pills. once i started a new pack, everything went great for the first two weeks. however, i started bleeding again midway into the third week. it was at that point, that the remaining patience i&#039;ve had for this pill was lost. yeah, this birth control truly does prevent pregnancy, because it prevents you from having sex in the first place, due to the never-ending shark week. :( i&#039;m switching to a stronger pill, because this is my fourth month on birth control, so i should not be bleeding this much."
