it'scalled the pregnancy mask... Google it
There is not much you can do for it...except use a scrub to try to take the top layer of skin off. They are called skin tags and many pregnant women get them. After the birth they will go away usually. But some women dont. You can get a chemical peel after you have your baby also. But not while pregnant.
Im 31+6 wks and just noticed a huge dark spot on my neck as well TODAY. hoping someone has some type of solution for this.
