Skin discoloration??

Please excuse my chapped lips 😬 I have a problem with picking them. After I became pregnant I started noticing this weird discoloration under my mouth. Anyone have any idea what it could be?? I’m also open to any information or tips on the rest of my face too (the redness, what it could be?). You won’t hurt my feelings. I use Cetaphil cleanser and moisturizer if it matters.
