Question for all mommies!

My OB/ midwife has scheduled for me to have a appointment in 4 weeks, on Oct 13. She said we will be doing my genetic testing, my normal prenatal scan and my first 1 hour sugar test. My sister just had her son, and they wouldn't give her a sugar test until she was 28 weeks, I'll only be 14 weeks at that point. Is this normal? When did you all have your first sugar test?
