Bunion or something else?

Shannon • Akash born 2015, baby girl due Dec 23rd

I started getting a bump below my big toe, on both feet. It feels bony, but it's not on the side of my foot like what I've seen online in pictures of bunions. I don't wear heels anymore and haven't for years, but I wear a lot of flats, and my feet are flat. Any ideas and what should I do? Thanks in advance!!!
