Birth Control
"My daughter had a good experience with her Implenon, however, 3 years later when she had to get it replaced they substituted the Implenon with a Nexplanon, this wasn&#039;t to her benefit. Approx. 3-6 months after the implant was performed her breast size went from a 32DDD to a 32H, without weight gain. We had it removed and the doctor found that it had broken in half inside her arm (something that is supposed to be next to impossible. Obviously, that was the reason for the sudden surge of hormones that caused her breast growth, which still remains 32H to this day (6 months later). As a nurse this concerns me as I know there could be other long term effects she may have to deal with."
