Hi Sarah,
Do you mind if I ask where in the UK you are based? My wife has recently been turned down for dexcom funding. We've been self funding it for over three years now and also trying for baby number two. My wife has issues with a lack of hypo awareness overnight which is one of the reasons we are self funding it. We've also had a miscarriage since trying so similar situation to yourself. Her HAB1C is uasually around the 6.0-6.5% mark thanks mainly to the help from the Dexcom. I think you will find the Dexcom really helpful. All the best.
