Odd redness

Hi ladies !

I’ve been having a rough week . I was diagnosed with the flu after two er visits and the following day after diagnosis I noticed this redness on my right breast. I got scared so I went to the GYN to get it looked at she said she doesn’t think it’s worrisome could be the flu she doesn’t feel lumps or bumps and the rash isn’t risen. But now it’s on my left breast too and I’m still worried . Let me know what you think ... something odd or just the flu? Also I have my nipples pierced could it be an infection? They don’t hurt, the rash doesn’t itch. My boobs hurt but that could be because I just got my period . There’s so many factors and I’m seriously freaked as you can see . Please help!
