Yeah i agree with Melanie. My bub was head down from fairly early on and i used to get some whopper of nudges down towards my pubic bone...thought i'd get bruised they were so strong.Try to find out the positioning when u go for ur next check up. I wouldn't stress too much about it, cause even if bub is feet down they can turn very quickly at the last minute...and there are heaps of girls on here that can provide u with exercises to help bub change position
