Signs of preeclampsia

So my doctor told me a couple weeks ago to watch out for major signs that indicate I could have it such as swelling, vision changes, and headaches. Well I've been having a few vision changes like randomly seeing spots as if I got up to fast kind of thing but the thing was I didn't get up too fast. I was either already up moving around or sitting. When I told her she asked if I had headaches which I didnt. Well lately I've been having a headache everyday now. My feet don't really seem swollen unless I've been on them all day which I know is pretty normal this far along (34 weeks) I can't really tell about my ankles and legs since well they are kinda thick as it is lol. My blood pressure has seem to be fine. Except last Friday she said it did seem a little high but then she redid it and it was fine. And they haven't said anything about any protein on my urine. So I'm not sure if I should call my doctor today and try and get in or just wait until Friday when I have another appointment. I also have a stuffy nose so I'm not sure if that could be causing the headaches but normally it doesn't when I've had it before. I hardly ever get headaches in fact. Opinions?
