1 doctor agrees

In brief: Yes

It's normal for a first trimester ultrasound to be different by 5 days and still be within the standard deviation of error. A fancy way of saying, that yes, it's okay that these 2 different gestational ages were given.
Your doctor will tell you which is the date he/she is going to go with for the remainder of the pregnancy.

In brief: Normal

Ultrasounds in pregnancy can be up to a week off of your dates.
Your OB will consider another ultrasound later for comparisons.
