Hello, it most likely isn't anything to worry about, but be on the safe side, and get it checked out. It prolly is only what is called a skin tag...
I had one... I got it removed, it was biopsied, to make sure it wasn't anything, or cancerous. It wasn't.
Don't worry, but do get things checked, your health is the most important, and your baby's too!!!!!!!!!!!!!!!!!!
God bless,
