Diabetes and pregnancy

So I just took a pregnancy test and it came out positive... however I have uncontrolled diabetes. I never took care of myself but knowing I'm growing my very own baby, I sat down and searched online for doctors hoping to give me meds and put me on Insulin (I know my blood sugar is extremely high) ASAP. I will call and make appointments early in the morning as all the offices are currently closed. I'm so scared and i know stressing isn't going to help either. I've had a miscarriage before and I had no clue I had diabetes... maybe that's why I lost my first pregnancy. It's time to get serious with my diet and exercise. Can anyone share their stories with me so I can reflect on it and hopefully put me on the path of a healthy pregnancy this time around?
