Low Blood Sugar

So I called to get the results of my glucose test that I did yesterday morning and it was 63...yea pretty low. The nurse I was on the phone with asked me if I was okay and how I was feeling. I told her I felt pretty crummy about 20 mins into the test but, started to feel better towards the end. She told me the steps I need to take for the remainder of my pregnancy but , to be honest Im freaking out. I was perfect with my daughter and this just scares me. Is this just pregnancy related? I have 0 family history of Diabetes and when I asked her if that had any link to low blood sugar she said it could be pre diabetic...great. If you had low blood sugar could you share your experience? Im trying not to get all worked up but I cant help it.
