Yep. My first dr told me I wouldn't get any other ultrasounds after 20 weeks unless something was wrong. Due to other circumstances I switched Drs and she said the same thing but because I have gd and didn't find out the gender of my baby I get one more at 36 weeks. They don't give them out unless you have a nice dr or pay for them or are high risk.
state lets u get an ultrasound but just one. unless it has to be checked then you get more then one. your not to far along so if ur baby is ok now they wont tell u about having another one.
