Breech at 26 weeks

Andrea • Second time mommy due June 2nd!
I noticed a decrease in fetal movements over several days and decided to get a sonogram to make sure everything was ok. Baby is perfectly healthy but in the breech position now. They said they won't worry until last few weeks of pregnancy but I get nervous since j barely can feel any movements now! I also have anterior placenta. Anybody else have similar issue?  I can't find any correlation online with minimal movements and breech at 26 weeks. Thanks in advance!
