How much do you get from 1st ultrasound?

Had my first u.s today at 7w 4 d.... Tech won't share any info with my husband and I; won't even show us the screen.  When I asked her, she said it is too early to hear a heart beat, and she only said "you are definitely pregnant." I was so paranoid especially, knowing that with my last pregnancy, I was able to hear my daughter heart beat at 6w 6d, and the tech printed some pics of the Ultra sound for us....I am worried, and nervous that something might be wrong.  Did any of you get an a** hole tech like mine?
