Hey ladies, I'm 21 weeks pregnant and I woke on Friday to a line diagonally across my vision in my left eye. This has progressed to flashing blue and purple lights, not constant, comes and goes. Headache but nothing too noticeable. I phoned maternity unit to see if it's normal and she said I need to get myself to an optician, if I went up there all they would do is check my blood pressure and urine so wouldn't really be worth while. Anyone any experience? xx
