A Day Through My Eyes

Have any of you ladies experienced a flashing senstion in your eyes after you close them? I have been a little sick the last few days and have been seeing weird constant flashing everytime I close my eyes. I read that this could be a symptom of pre-eclampsia but I'm only 11wks. I haven't experienced this before and I'm at but worried. Today is a Sunday so no doctors are open! Anyone else experience this?
