High blood sugar 21 weeks

Deirdre
I am 21 w 5 days. Woke up not feeling well. Very nauseous and dizzy. Threw up my breakfast. My 18 year old son is diabetic and suggested I check my blood sugar. I did and the first reading was 256 so rechecked. Second reading was 169. Both are high readings for a non diabetic. Should I call the on call doctor or just wait until the office opens tomorrow?
