My retinopathy progressed to proliferative at around the same stage of my second pregnancy - 6 weeks - or at least that's when it was picked up on my annual screening. I think tightening up my control for pregnancy is what caused it to progress. I was rushed straight in to the specialist eye clinic for a laser appointment, but I didn't need it just yet. I was seen every month throughout pregnancy and each time was a laser appointment so they could do it straight away if needed, but it remained stable throughout and since (touch wood) and so I am now on 4 monthly reviews again and baby is now 26 months. I too was completely panicked and freaked out convinced I was going to lose my sight but it has been ok so far. I hope it will be the same for you! Good luck x
