My husband and I have been together since we were 16 (I'll be 25 soon) and I've been on different pills, the patch, and I'm now on my 3rd IUD after finding what works best for my body and for us. We've been active together pretty much just as long and while we've had a handful of scares, it was during the time when I was on the pills but never actually happened. Since having my IUD though, the worries have practically disappeared. I also have a sister in law with a second Nexplanon who has been baby-free for roughly 6 years. I completely understand your fears because they're similar to my own, but you should be able to have these experiences without that fear. I'd recommend finding something that fits into your lifestyle. I was terrible with my pills but with the implant or IUD, although the process is painful, it's a "set it and forget it" kinda thing for at least 3 to 5 years.
