Feeling worried

I'm just 5 weeks along and already had a gyn appointment to confirm the pregnancy and run tests. On Sunday I took the glucose test early since my mother has a history of diabetes, so the sooner the better. Normally they don't do the test till you're about 24 weeks. My glucose test came back as slightly elevated :-( and I'll be going back for a 3 hour test to get a better reading. Is or has anyone else gone through this as well? Did you have a healthy delivery or were there many complications?
