Not likely: If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy. Nexplanon failures are very rare as it is most effective reversible birth control available. Diarrhea is not a typical symptom of pregnancy and may indicate a digestive disorder if it continues.

Always possible: Whenever you have sexual intercourse there is a risk of becoming pregnant (even on birth control-though the risk is much lower). Your diarrhea is a non-specific finding. The best way to find out is to check a urine pregnancy test. Depending on the test, you can usually start checking a few days before your expected next period.
