in the first pick I thought "omg ballz", but then after i saw the other two Im not so sure because yea.. it can be kind of tough to take pictures of such little detail.
heres a trick (From my other hobby of photography.) try using your macro setting on your camera because it will take a much better picture for us to see. that should help. unless thats what you used in which case, try again? or wait a few more days till its more significant. I wouldnt stress out about pollen just yet. they still look pretty tiny if they are indeed balls.
