I got the Naxplona in March.. And bleed only for a week after getting it on my arm.. Well I got my period and I'm going on my 4th week of having my period. One minute it let up and I think Its over with and the next I'm having a heavy flow? Is it normal? Is there a wait to lighting it to stop it. I'm starting to become miserable. I want to switch but should I wait it out?
