I am on my fourth day with a headache. They last from the point I physically get up in the morning until I go to sleep. My first day, Thursday, I had blurred vision in my left eye, sort of like I looked at the sun for to long. It lasted about 15 min. The same happened to my right eye the following day. It has not happened since. I am 27 and 37 weeks pregnant... I freaked out on Thursday thinking it was preeclampsia but was not, my on said if it happened again to see a neurologist but I have read that this can be common... Has this happened to anyone else?
