Diabetic with fertility issues

My husband and I have been trying for a year now and have now started going to fertility specialist.  This would be my 2nd child, my daughter,who i conceived naturally when I was 21 is a happy healthy 10 year old but I have forever longed for 1 more. My husband has no children the problem is I have type 1 diabetes and high blood pressure. I am not doing any of this without the permission of my team of doctors but other than my husband and his family I don't have any support from my own. I guess my question is, is there anyone out there with similar illnesses who are having trouble conceiving?
