"loved it as a contraceptive, didn&#039;t so much love the weight gain. didn&#039;t get pregnant so it did the job! i suffered severe ovarian cysts in the past (3 surgeries before age 17) and was on microgynon 30/50 tablets for 4 years. decided to opt for implanon purely for convenience, and initially it was terrific. no side effects except weight gain. i had it from january 2014 to december 2014, had one period in that time (used to be 28 days on the dot). absolutely fantastic, but i was slowly gaining weight despite eating the healthiest i have and going to the gym at least three times a week. spoke to my doc, she said i was unfortunately in the teeny tiny minority that just packed on weight. whipped it out there and then, now back on microgynon."
