Dry skin on face??

So this has never happened to me before. I have dry spots of skin all around my mouth and I'm not sure why. I thought maybe it might be the cold weather considering its January, but I also don't go outside very often so idk about that. Then I thought about pregnancy. I'm 26 weeks and I know pregnancy takes moisture from your abdomen, but I can't see how it would make my face dry. Putting lotion on these spots makes them burn too. I tried using aquaphor, the skin healing ointment, but it doesn't seem to be helping. Any idea why I have these spots and how to get them to go away?

Side note: As you can see my lips aren't chapped, so it can't have anything to do with that. I put chapstick on religiously so theres no need to lick my lips either, which we all know can cause redness around the mouth.
