Should I change Ob's?

Leanna
 On 11/19 I had my first ultrasound scheduled for 3pm. At 8:45am I received a phone call saying my doctor had something come up and my appointment has to be rescheduled. I had planned on working half the day to keep from losing hours at work but anyway I was able to get off all day and go in that morning. I waited on my doctor for almost 3 hours. When I finally got to a room for the actual ultrasound, it was done in less than 10mins. She didn't really ask me any questions or spend time with me and that makes me nervous considering this is my first baby and pregnancy. That night I was talking to a girl I know whose sister used the same dr for her second pregnancy and she said her sister experienced the same thing as far as the dr rushing to get done and rescheduling appointments. Yesterday I googled my dr and found out lots of people haven't had the best experience with her. The dr I'm thinking about changing to is fantastic from what I've seen on google and heard from other people that have used him. Any advice??? The first pic is my doctors reviews and the second is the doctor I may change to reviews
