so i got the nexplanon implant nov. 22, my doc said if i want to have sex use a condom until the nexplanon becomes effective a week after it was inserted, so i waited the whole week (no sex) and a few days ago i had sex for the first time with the nexplanon now working and my boyfriend came inside me, i know it’s working but i’m still a little scared, is nexplanon 100% effective ??? do you guys think there’s a possibility of pregnancy ???
