Is it typical to develop one flat tiny red spot on your breast during pregnancy? it is a bright red dot. i put a picture in my profile file. will it go away?

Doctor can examine: To ask, "Is it typical to develop one flat tiny red spot on your breast," is to ask, "Do most women get one flat tiny red spot on a breast during pregnancy?" Haven't heard of that happening to "most women." Otherwise, it would be a well known entity. There is however such a thing as spots of blood vessels called pregnancy hemangiomas (can Google it). Best to have the Ob-Gyn see the spot in-person.
