There is a lot of discussion suggesting that diabetes does impact fertility but likewise there are many people who have no problems at all. I had some rather complex issues unrelated to my diabetes, I struggled with these for 5 years, finally and thankfully these were resolved last year and when I was given the go ahead to TTC, i conceived within 2 months - I am 38 years old, type 1 for 17 years. So please dont let statistics worry you. Agree good hb1ac before and throughout pregnancy is important (I unfortunately conceived on high hb1ac - so very worried at the moment). Also, daily exercise, walking helps as it improves insulin sensitivity, insulin pump, I am 16 weeks pregnant but not on the pump
Folic acid high dose 4 or 5 mg daily, and vitamins, like pregnacare max, should be started before you TTC, I found out at 4 weeks and have been taking them since. Healthy diet including fresh fruit and veg and keeping up to date with all your diabetic appointments for retinopathy and neuropathy - even women who dont have any retinopathy before pregnancy are advised to have eye screening every trimester as diabetes complications can develop or worsen during pregnancy. However if you have stable and good control before u conceive this is less of a concern
In terms of fertility - usually the NHS will prioritise you if you are diabetic and have been trying for 1 year or so
I took clomid, a tablet you take at home for a few days at the start of the menstrual cycle, this is the first line of treatment for healthy women trying to get pregnant who havent been successful. Hopefully you wont need this - wish you all the best - good luck
