Ultrasound dates off from LMP dates?

Question

I had my first ultrasound (transvaginal) on the 28th, we saw baby and doctor said the heart rate was in the 130s.
According to lmp that day I should be 7w5d but baby measured 6w. 
My period started 11/4 and we only baby danced once, a few days before thanksgiving.
Does anyone else have experience with baby’s dates being different and still being ok?
