Nexplanon or natural family planning?


I got on the Nexplanon implant in December after getting engaged and deciding we wanted a more permanent method of bc other than natural family planning like we had been doing. I’ve also been really focused on a healthy lifestyle and losing weight (currently down 30 pounds!!!) for the wedding and just overall wellness. Recently I’ve been seeing more and more about how poisonous BC is and i am about ready to rip the damn thing out myself. I guess I’m looking for advice on both sides. Should i keep the Nexplanon in until the wedding to make sure we don’t have an accident or should i take it out for my health and go back to NFP?
