This is my 4th pregnancy, all others have been very simple with no problems at all. This time though I am having awful headaches. Every two or three weeks I will have an awful migraine with aura - a blind spot in one eye, then so Ill I have to lye in bed for two or three hours, but the rest of the time I just have a general headache. I feel like I cant concentrate or focus. Dr says it is just pregnancy that is causing it and it will go away after birth. Any other people had this? Any suggestions?
