That is a great question! Lets talk a little bit about the Nexplanon.
The Nexplanon is a single matchstick-sized rod that is placed underneath the skin in your upper arm. A nurse or doctor inserts the rod. Once inserted, the rod releases hormones gradually for up to three years.
Nexplanon is 99% effective in preventing pregnancy for up to three years, but it does not protect against any STIs!
What is important to know is that pregnancy is possible as soon as the Nexplanon is removed. It is also recommended to refrain from any unprotected vaginal intercourse for at least 5 days prior to the removal of the Nexplanon. This is because sperm can live in the vagina for 5 days. So if unprotected sex occurs during this time, pregnancy can be possible.
It is also important to know that unless you are practicing the natural family planning method, it can be extremely difficult, if not impossible to know when exactly you are ovulating. This means that even if you keep a period calendar, you need to be also keeping track of ovulation by doing things like taking your temperature and checking your cervical mucus daily. This method is often used after consulting a doctor. A doctor would advise you on how to correctly use this method.
The only way someone can know if they are pregnant is to take a test at least 14 days after the most recent sexual contact. The result can be trusted then.
