Baby scans

I had my scans done on the 7th to see is everything okay they couldn’t find out the sex due to where the baby sitting the head is already down and the baby back is towards my stomach I been having y braxton hicks already this is my 3rd baby and I’m 20weeks&4Days gone. My question is, is it normally get braxton hick now? And baby head being really low at this many weeks?

With my two girls there head wasn’t low until near there due day...
