Am 18 weeks, just wondered if this sounded like anything familiar...I've been waking up over the last few weeks seeing a pink and blue kind of textured pattern (think pink circles behind blue diagonal lines). It usually coincides with a minor headache that disappears when I take paracetamol. I do normally suffer migraines but no visual disturbances and this isn't a migraine. Is it just another weird pregnancy thing / anybody else have anything similar?
