32 weeks baby head measuring small

This is my 3rd baby & I have never been told of my babies having a small head with the other 2 pregnancies. Today at my appointment they told me babies head was in the 7th percentile and we will recheck in 4 weeks. She said there are no other indicators of anything & baby overall was measuring 48th percentile so I shouldn't worry. Of course harder said than done as this pregnancy has thrown quite a few curve balls at us. Has anyone had the same thing happen & everything was fine?
