Are you also worried about this like Enrica? The subdermal implant does not contain estrogen, but only the progestin etonogestrel. It has the same mechanism of action as the progestin-only pill, but has the advantage of providing long-term contraception for 3 years. Once implanted, there is no need to remember to take a pill every day. It is recommended in all situations where you are not able or willing to use estrogen.
