While the Nexplanon rod may not immediately cause problems once it is expired, you should definitely have it removed. The rod is still releasing hormones while it is inserted, even if the hormones are not at a high enough level to prevent pregnancy. If you were to start another form of birth control at this time, you could potentially give yourself a harmful level of hormones by combining the leftover Nexplanon hormones and the full dose of the new birth control.
Additionally, when something non-natural is inserted into the body, the body tries to get rid of it. Over the course of time your body will try to expel the rod, and it could move through your body to a place where it is unable to be reached without X-ray and surgery. Avoid this. Just get it removed.
If you’re too uncomfortable with the idea of having a pap smear right now (although if you’re due for it you should definitely get it done to protect yourself), you can make an appointment to get just get the Nexplanon removed. If the provider says, “Well, you’re also due for a pap smear, let’s just get that done while you’re in here,” you can say, “No thank you, I’m not prepared for that just yet. I’ll make an appointment on my way out to have a pap smear later.”
You have the right to refuse care, even if it sounds like it’s mandatory.
We need better sex ed because I didn’t know that periods that cause excruciating pain, among other things wasn’t normal. I didn’t learn about the many common problems women could encounter from menstruating from sex ed. I learned it from the internet.
"It’s not your body anymore, it’s the fetus’ too."
Actually no. I feel awful for the children whose parents teach them that there are circumstances under which their body is no longer their own. If I ever have a daughter, I will teach her that her body is HERS no matter what and she is absolutely in control of who and what touches/uses it at ANY time.
