Normal or no ??

Not sure if it's worth mentioning to my doctor, or just a normal part of pregnancy. This is my first so I'm still learning, opinions appreciated ☺️ I have an appointment tomorrow.
I will be 30 weeks and 3 days. And for the last few days, on and off, I've had intense swelling in my face and hands. Usually they'll get pretty swollen and then go back down to normal after a couple of hours. Is that suppose to happen? Thanks in advance!
