"i had implanon inserted in december of 2009. the first two months i did not get a period but since then i have gotten it every 2 weeks. and it isn&#039;t just spotting, it&#039;s a full period with pms lasting around 5 days. i talked to my health care provider and was put on apri along with the implanon in order to regulate the bleeding which my hcp said should regulate in about a month. other than this, the only side effects i&#039;ve gotten are increased appetite but with no weight gain and my skin has cleared up."
