Sudden blurry vision?

Ra

I have suddenly got a very blurry vision on my right eye after having a nap. Currently 35+1 weeks pregnant and I have had slightly elevated blood pressure during my pregnancy. Of course according to google it could be a sign of preeclampsia but I have no other symptoms and I only have blurry vision in one eye not both. Has anyone else experienced this? If my vision does not get better by tomorrow I will be contacting my doctor.
