Lump?

Hey y’all, so i have a under the surface lump and I’m making an appointment to get it checked or. It’s about the size of a nickel and it doesn’t hurt and you can’t see it but i can feel it. I looked to see if there was a matching one on the other side cuz i thought Mabey it was a muscle and nope there’s not. I looked at some reputable sites and it seems to be too high up and over to be a cyst of any sort. Is cancer a possiblity? Also it’s located about an inch to the right of my clit. Any thoughts are appreciated! I️ am n the nexplanon implant as birth control
