Sun exposure after traditional ablative CO2 laser done a month and a half ago, did I cause damage? (photo)

I had traditional ablative co2 laser done on my cheek for a scar a month and a half ago. Yesterday I was outside for a few hours while it was very cloudy with light rain, I had SPF 55 on my face to try and protect the treated area. I noticed this morning a part of the treated area is more red than before. I'm worried I caused damage to my skin even though I wore SPF and it was very cloudy and I couldn't see the sun through the clouds. Please give me advice on what I should do, I'm so worried.
