3 days post c section with one swollen foot?

Hey, I'm just 3 days post partum after my third cesarean. I have some mild/moderate swelling in my right foot. It doesnt particularly hurt, no discoloration, but definitely retaining fluid in that foot, from the ankle down. My left foot and leg is completely normal. No swelling at all. I had googled the swelling to see what I can do to help alleviate the water retention a little faster, and several of the articles I read said that it's totally normal, but that it should not be in just one foot, but be symmetrical. Now I'm paranoid and scared. I'll be calling the ob tomorrow, just to be sure, but can anyone give me any info in the meantime? Hoping it's nothing 🙏
