Dizziness?

I’m 33 weeks and for the past couple weeks I’ve been dealing with blood sugar issues (not gestational diabetes) and it causes me to feel really lightheaded and dizzy. Today however, feel more dizzy than I ever have and I legit feel like I’m gonna pass out. I checked my blood sugar and my pulse and my oxygen levels and everything is normal. I drink plenty of water and my urine is super pale, so I know I’m not dehydrated. But I still feel REALLY dizzy and like I’m gonna pass out. Any ideas as to what’s going on????
