should I get a new doctor?

Not sure if I'm just overreacting. This is my second pregnancy. At my first appointment my doctor told me he wanted me to wait until I was at least 20 weeks to have my first ultrasound but the nurse convinced him other wise. I had my second prenatal (I was 16 weeks) on Thursday. All he did was listen to the heart beat and tell me it was in the "130s". He didn't tell me an exact number and I'm pretty sure he didn't even know an exact number. He didn't measure where my uterus was, only guessed that it was at the right spot to listen to the heart beat. He also has it that I'm okay to lift 50lbs at work. Is this all okay or am I just over reacting? 
My FIRST doctor for my FIRST pregnancy gave me four ultrasounds by the time I was 22 weeks because he wanted to make sure everything was going nicely and that no mistakes were made. And he would always check my uterus and give me an exact number for the heartbeat.
Not sure if I was just "spoiled" by the first doctor or if this doctor isn't that great. I go to a place with resident doctors so it wouldn't be hard to switch.
