Doctor wasn't worried about blood pressure?

Basically at my 34 week appointment i explained to the doctor that i was having horrible migraines and he gave me magnesium oxide for it. My blood pressure there read 124/81.

They urine tested me and found 1+ protein in my urine but also things that indicated a UTI so he prescribed me antibiotics and sent me home. Was my blood pressure not considered high? Should the doctor have been worried? I also have GD so i heard im more at risk for high blood pressure
