Just keep a close eye on your sugars and get them in range (70-140) as soon as you can. We're type 1, and highs happen. Treating them as quickly as possible is important.
I blogged extensively about my healthy type 1 pregnancy and am writing a book about the subject that will be out next year. There are also support groups through Yahoo (Positive Diabetic Pregnancies and PregnantPumpers are two good ones) where you can get more immediate support. There's also diabeticmommy.com.
Good luck--you can do it!
