Pregnant.....UNEXPECTEDLY!

Hello Everyone!  I've been a member of this site for awhile, but never posted anything....However, I just found out on May 7th that I am pregnant!  This was quite a shock since I just got married March 24th!  So needless to say, our lives are changing ALOT!!  I have a 5 1/2 year old little girl and was diagnosed with T1 about 3 months after she was born.  I am soooo scared.  I have maintained an A1C below 7 since I was diagnosed.  I have an OBGY/N  and endo appointment at the end of this month....Any tips/advice on being pregnant with T1?  When to worry and not?  ANYTHING will help at this point!!  Thanks everyone!!
