Went in for my checkup and..

So I went in for my weekly check up (i'll be 36wks tomorrow) and baby boy is head down, has been for awhile. They checked me and I'm not dialated any but I am 30% effaced. He also was shocked because he could feel the babes head and said that he has dropped significantly, but he's not my normal OB so he didn't really go into very much detail. But, is it normal for them to be able to feel the baby's head and not be dialated at all? I have another apointment not this coming monday, but the following with my normal OB, so I guess I'll learn more then.
