I'm in my 28th week. I'm glad I made it up to this point, as my son was born at 28wks! But this morning, I woke up with blurred vision

And i recall getting this blurred vision before everything went downhill with my son!! So now I'm freaked out and worried out of my mind!! I was suppose to get my blood pressure checked at the pharmacy today, but i forgot...can't believe i forgot!! I don't get to see my OB until tuesday. And I've left a messege with the nurse, but i didn't hear back from her today.
I know that blurred vision could mean alot of things. But i also know that this is one of the symptoms of pre-eclampsia

I'm so worried!! At the same time, I am too scared to get checked out because i'm afraid of being admitted to the hospital right away!
