"i got the implant at the beginning of october, 2015 on the last day of my period. two weeks later i started bleeding again and have been bleeding since. its february 2016.... my doctor gave me a prescription of estrogen a week ago to counter act and try to stop/get the bleeding under control. i have to take it for 14 days. so far, the bleeding is way lighter, but i still have to wear a tampon or pad all the time. it&#039;s very frustrating. some other side effects i&#039;ve had are sweating really bad while i&#039;m sleeping, having trouble sleeping or staying asleep, crying over stupid things i normally would not cry over. as for weight i&#039;ve gained probably 6 pounds so far. i rated it a 9 because it is effective despite the side effects."
