So I just got the implant in my arm, and as I changed my method of birth control on <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> to the implant, I noticed my fertility days disappeared. Should I still be cautious in the general 2 week time frame after each period, that would be considered my fertile days, or should I not worry and let the implant do its thing?
