"i got my implanon in december of last year, and i had no problems with getting it put in. it was painless and i thought that this one was going to work. i had no problems with it until late february, 2 months latter. when period started later and continued until 2 weeks ago, i had been on a constant period months straight. it was horribly painful and i cannot wait till i get it out in a year and a half."
