Weirdness going on

So I have noticed my vision getting blurry a lot lately and I'll see black spots every now and then and I get real dizzy and I almost lost my balance today because of it and I keep getting these headaches that last for days. Since it's Sunday my dr is closed but I plan on calling tomorrow but I was looking up my symptoms and preeclampsia keeps popping up and now I'm getting a bit worried. 
Has anybody had these symptoms and it not been serious or what did your doctors say?
