TMI-what does this mean?

Suprena

So I am currently 8DPO with generally a shorter cycle of 23/24 days. This is my first month officially tracking, 2nd TTC. AF is due in 3/4 days. Well this morning I woke up to this noticeable change on my breast (pic in comments). Anyone experience something similar? I've heard of darkening of the areola, but not a white halo like around. 🤔

My breast are swollen and only slightly tender as they usually get before AF. I have experienced consistent one sided dull cramping since 4DPO up until yesterday. Usually only cramp a day or so before AF. Also headaches and fatigue. Anyone experience this and have a good outcome?
