Pregnant on implanon/nexplanon?

Has anyone here gotten pregnant while on implanon or nexplanon? I know your periods become irregular or nonexistent but I’ve had mine in for almost 5 months and I haven’t gotten my period this month. My last period was only two days long and now I’m ten days late. I’ve been crampy all day and I don’t normally have cramps on my period. I’ve been exhausted all week, I’m so tired I feel like I drank NyQuil or something and this is an all day thing. My son seems extra clingy, I’m grossed out by a lot of food, and I’ve been extra hungry. I know nexplanon is SUPER effective but I just feel like something is off😩 im gonna test in the morning
