Have any of you noticed changes to breasts afterwards? I’m 7 months out from my SA and worried

I have a bluish-green bruise-colored ring around one of my areolas. Not sure how long it’s been there

I’m currently uninsured until August when I start a new program, so I’m most likely going to hold off on an appointment unless it is strongly advised to get this checked out.
I don’t feel any lumps but I’ve honestly never really learned how to properly check my breasts and I’m very squeamish of feeling the tissue underneath.
The red blotches are because I just showered. I censored my nipples but historically one has always been larger than the other, and I’ve always noticed them being slightly different colors as well.
My grandmother passed from breast cancer in her 40’s but I’ve never tested for the BRCA genotype. I tried to look it up but couldn’t find any matching images that looked similar, but maybe an explanation that it’s hormone related? I’m 26 and started hormonal birth control (Vienva) at the beginning of this year following a failed pregnancy.

Please share your thoughts if willing. Bless you all
