I'miinterested in birth control that does not prevent implantation of a fertilized egg (which all hormonal and iud methods do). I did some research and the only other thing out there is condoms and other barriers, or sterilization. I'm okay with not having biological kids - maybe I can get Essure (non surgical tubal ligation) and use it with condoms for max effectiveness? I'm only 22 though. Anyone else have experience with Essure? I heard it's difficult to get if you're young.
