Size of baby 11w2d

Is my peanut a good size for time frame ? This was an abdominal ultrasound. HR was 171. I keep seeing other pictures and they all look so much bigger. :/

They weren’t going to do an ultrasound so it was quick. The nurse couldn’t find heart beat with Doppler so she called the doctor in quick to find it on ultrasound. Didn’t really get to ask many questions.
