Kaiser people

Liz • Korbin John 11/17/2016

I have kaiser and of course haven’t had an ultrasound since the anatomy one around 21 weeks, is there another one? I don’t remember with my boy but my dr said my next appointment (which is Wednesday and I’ll be just over 35 weeks) said they will check to see if my girl is head down. Is that just by feeling the tummy or will they do an US? Also- when do they start checking for dilation ect? Thanks ladies.
