@sarahm723 As I've mentioned, there are ladies here who have have varying degrees of retinopathy and have had a baby. Bear in mind they might take a while to,reply as they could be busy with family or infrequent visitors to the forum.
The best thing to do, in my opinion, is to get your current eye problems dealt with; speak to your eye specialist about pregnancy and get their advice; also get their advice about supoort in lowering your blood sugar slowly so,it doesn't hurt your eyes.
Once you have a plan with the help of your specialists, then ask about a pre-conception clinic.
Nobody can predict how pregnancy will affect your eyes, but your specialists will be best placed to,give you an idea.
I'd also speak to,your DSN so they know your plans and can give you as much supoort as you need in gradually reducing your blood sugars. For example, you might be able to get regular appointments to help you. You could also ask about things like a pump to,see if that would help you gradually gain the control you need to,be pregnant.
