birth control
"I had had Implanon for a year and at first it was fine. Some breakthrough bleeding but eventually got to regular periods. And when closing in on a year with the implant I had my period for a month. I can't describe the difference in the period either, it was excessive. 
This birth control does what it is supposed to but with side effects. I had a good 8 months on it but I am getting it out next week. No woman wants to be on their period like that and never knowing when to expect it or how long it will last."
