Breast redness?? Please help!!

Lorean

Hi everyone, I’m 18 weeks pregnant with my first. I normally have large breasts (DD prepregnancy) and obviously they’ve gotten a bit larger so far. I have noticed though, for a few months now, some redness in the same spot on both breasts. It’s kind of in the cleavage area in between both breasts and goes all the way to my areolas. Where it touches my areolas, they feel almost thick. It’s not painful, not itchy but i actually just noticed today it feels a little numb in those spots. No lumps I can feel, just wondering if anyone has any idea what this is or if they experienced the same. I’ve googled and can’t find a single thing that sounds like it. The midwife says she’s not super worried but I’m getting increasingly more nervous since it’s not going away.
