I'm nearly 31 weeks. About 15-20 minutes ago, I developed, very suddenly, a weird blind spot - if I stare at the centre of my palm, I can't see the left hand side. It's making reading and typing very hard - and interfering with my MNing! Never had anything like this before. Should I be worried? Don't want to call NHS Direct because they'll tell me to see a doctor to be on the safe side. Could call my dad (retired GP), though he'll probably just tell me it's nothing to worry about. I have another hour at work to kill and will probably go mad if I can't read!
