abbreviations on ultrasound

[bat8301]

Since I had a second trimester miscarriage, I have been watched closely with this pregnancy. I have been taken daily progesterone IM injections- ouch. I recently went for my first ultrasound. I was estimated to be 6 weeks at the time. Of course I'm a nervous nelly about everything. They did see a heart beat, but no yolk sac. Is that bad? I also noticed on the pic I got "HAR- low". Does anyone know what that means?

Thanks in advance

I'm not entirely sure but I think it's to do with the US resolution.
