Has anyone ever gotten pregnant with nexplanon implant?

So iv had the nexplanon implant for over a year and I have been feeling very weird lately. I get cramps, I feel nauseous, today I fainted which has never happened before and I am very moody and emotional. I really think I could be pregnant but iv heard it's very rare to get pregnant with this birth control. Does anyone have any experience with nexplanon or know anyone who has gotten pregnant with it?
