What were your symptoms of preeclampsia?

My last appointment was at 34 weeks and everything seemed fine but since then I started getting occasional blurry vision, swollen feet (which hasn't happened my entire pregnancy) and headaches, which I heard were all signs but I also heard it usually developes around 32 weeks so I don't know if it's too late for it to develop? I have my 36 week appointment in the morning and am hoping everything's fine but I'd like to know, if you had preeclampsia what were your signs??
