"i got the implant in january of this year i was a hundred and fifty pounds and by the time i got it out in october i was a hundred and seventy i&#039;m having severe mood swings. this is a very effective form of birth control and i also didn&#039;t have any periods at all but the weight gain was terrible. after two weeks out i&#039;ve lost 5pounds not doing anything a lot of it was water weight as i was up peeing several times a night. i feel so much better already i&#039;m giving my body some time then i&#039;ll be going on the patch. the weight gain wasn&#039;t as bad as the depo shot but the mood swings were the same"
