Should I be worried?? Preclampsia??

Shelby
I'm 37 weeks pregnant and been going to my doctors appointments regularly. Every appt my BP is normal but I'm starting to worry. I've had consistent headaches that I have not had throughout pregnancy so far at all, I've had more swelling in my face but not as much in hands and feet until after working all day. Other then the headaches I've been extremely naseous the last few days and been seeing spots and getting dizzy frequently. Another concern I have is that the last two weekly appointments I've gained 3 pounds a week, which I feel like is a lot and I wasn't doing before. I'm wondering if I should be worried and call my doctor or if I should wait until my appointment 2 days from now. Please help!!
