Dont like my ultrasound tech

Cecilia
I really don't like my ultrasound tech she is very nice but when she goes to take a picture it is so blurry and you can't see anything.. I am not sure if I should ask for someone else or does the pictures not even matter.. Since I been pregnant I only got 1 good picture of my baby boy and it was for my dating scan which was a different tech.. I am now 28 weeks and I can't even show off the pictures because I am embarrassed of them..
