Face swelling @ 19 weeks

I’ve noticed the last few days my face (cheeks) have been swelling. I was underweight pre-pregnancy (5’6 and 110 pounds) so to gain any sort of weight is obvious. I’ve read that face weight-gain is common in pregnancy but only after 20 weeks. Should I be concerned? I don’t have another appointment for another week and a half.

Extra info: I know how your body handles pregnancy can be genetic. My mom gained a LOT in her face but it wasn’t until the third trimester. I’ve also only gained about 8 pounds total. ETA: I’ve also had lower or normal blood pressure at every reading.
