"i got the nexpanon inserted a month after giving birth, during that month i lost all my baby weight. after that i gained it all back and then some, i&#039;ve worked out and watched my portions but nothing has helped. i don&#039;t have a period but i also breastfeed so it could be due to that. the only good thing about the birth control is that it works. it has also caused terrible depression and mood swings."
