"i got the implant june 2014 and i started my cycle about 3 weeks later and it was normal. the next month i was getting married on the week my cycle was suppose to start so my doctor gave me some meds to help hold it off for a week and it worked. november was the first month that my cycle lasted 28 days after that it&#039;s been like 2 to 4 weeks of bleeding 2 to 4 weeks off. i went to my doctor june 2015 and she put me on meds for 3 months to help give me a break from bleeding. the first month on the meds my cycle lasted about 34 days the 2nd month was 3 weeks long and so was the third month. i haven&#039;t had a break from bleeding at all and i can&#039;t tell you when i had  a cycle longer then 3 weeks without bleeding."
