Written by Stephanie McClane

What is Nexplanon?

Nexplanon is a etonogestrel implant. It is birth control implant that controls pregnancy for up to three years and is said to be effective 99% of the time. Nexplanon is a thin, flexible and small arm implant that is in the size of a match stick. It is a long action birth control method. Nexplanon is placed carefully under the skin of your inner upper arm, by your by your health care provider. It is totally reversible and you can get pregnant after its removal.

How Does Nexplanon Work?

Nexplanon contains etonogestrel. Etonogestrel is the synthetic form of naturally occurring female hormone, progesterone. Nexplanon releases etonogestrel into the blood stream of the implant. The main way in which Nexplanon prevents pregnancy is that it releases high amount of synthetic progesterone, tricking the body into believing that ovulation has already occurred and prevents the eggs from being formed in the ovary. Etonogestrel also effects the natural mucus at the cervix. This increases the thickness of the mucus making it difficult for the sperm to enter the womb and hence successful fertilization.

The chances of getting pregnant on Nexplanon are very rare but it is technically possible. But you should know that the side effects just after the implantation of Nexplanon can mimic the symptoms of pregnancy as the body is not usually used to the hormones at that time.

Hi, I’m Stephanie. I graduated college with a business degree and a minor in biology. I met my husband at a business convention and was happily marriage and pregnant within the first two years after saying the words “ I do”.

Jennifer is the eldest of the three. Being pregnant with her, my first, I researched everything pregnancy related and read nearly every book. Giving birth to Anthony and Matty seemed more natural and less stressful the third time around.

I’m happy to share what knowledge I have gathered and learn new things from other mothers. From morning sickness to Anencephaly, or potty training to thumb sucking, I have books and resource guides to share.
