How do you like your doctor?

Sometimes I think my doctor is too young and not experienced. She's 32 and no kids herself, she's a scatter brain sometimes and I think she doesn't pay enough attention, this is our 3rd pregnancy and I have stayed the same weight the entire time and my belly measures a week small. I've been hinting to her my weight never changes and I think I'm having a small baby but she won't give me anymore ultrasounds (I had 2@ 9w & 20w) unless I spike blood pressure or something crazy. Not sure why it's so hard to give me a third term ultrasound. My last pregnancies I've gained 15-25lbs, she always looks at my past history and this pregnancy I've been low blood sugar and no weight gain. I don't know maybe I'm paranoidđŸ˜” Do you like your doctor?
