Anal growth...?

So I am 33 weeks along. I have some type of growth on the outside of my butthole. It doesn’t hurt or bother me at all. I really don’t think it’s a hemorrhoid, but looks and feels more like a skin tag. I do feel like it’s getting larger. Is this something I can address with my OB? I have an appointment with him next week. I just hate to make an appointment with my general doctor to check out my butt lol.
