WHAT CAN THIS BE????

What the heck can this be? And did my pregnancy cause it???? It doesn’t hurt, but it’s ugly and it’s bothering me! I never even noticed it till my husband pointed it out today! (ITS FEET PIC) Im sorry for my hideous feet btw lol. And yes yes I’m aware my feet are dry lol. It’s on my pinky toe!!!! It feels like boney/hard??? Like it’s so hard to explain! 😅😅
