"i have been on this birth control for a month today. i was already having heavy bleeding prior to my dr prescribing this birth control. the next day i started the pill i stopped bleeding for a whole wk then the second week i began to spot. followed my the third week my period started to be heavy all over again with quarter size blood clots. i contacted my dr he said that my body is still trying to get used to the pill give it some time. this week again i called the dr back because the bleeding seems to be getting worst and the cramps are on a level of 20 he said again just keep taking them and as the new month is approaching a change can occur if not contact him again. i sure hope this pill works fast &amp; stop the bleeding."
