Recently on my left breast I noticed a very tiny dark spot on my . I can feel when I put my finger on it that its like a small bump but no notably extra added skin or anything like a skin tag. Its itchy when i wear a certain bra. I've changed bra's since then and have had no itches since but its still there. I know a lot of things that go on during pregnancy are usually hormone related but figured maybe someone could shed some light on what it might be until i go to my next OB appointment.
