"i got the implant on may 21,  2015 and it is now the 27th. the insertion wasn&#039;t as painful as i thought it would be thankfully, but the day after my arm was swollen and bruised. there is still a significant amount of bruising almost a week later.  now i haven&#039;t bled any since i&#039;ve had it inserted but the mood swings have been horrifying.  one minuet i&#039;m super happy and then the next i&#039;m bawling my eyes out.  i&#039;m always irratible and it doesn&#039;t take much to aggravate me anymore.  other than that i&#039;ve had no weight gain,  no break outs,  or anything awful. i really like this form of birth control and plan to keep it.  hopefully nothing changes besides the mood swings getting better.  i hope this helps."
