Seeing spots/lights 32 weeks

Sometimes I will see little bright flashing dots, sometimes it’s just a few but other times there is a lot and I’ll feel off in my head/body. I’ve also been having breathing issues but I think that could be asthma. Every time I’ve been to the doctor my blood pressure has been fine, and I don’t have GD. Just wondering if I should mention this at my doctor’s appointment tomorrow because I seen that seeing spots/lights is a symptom of preeclampsia, but I don’t think I have any other symptoms.
