Hard to tell from your description. Different grain bills and different yeast strains can cause the fermentation to appear different.
If there is no thin coating covering your wort, I'd say it's just yeast rafts. An infected beer often has this thin pale coating floating on top with maybe a couple of largish bubbles trapped in it. White specks with small bubbles stuck to it sounds like yeast bits to me.
As Arnoldk2 says, give it a taste and see if it's excessively tart or yucky. If you like the taste then all is good. (Because you can't be harmed by anything that might grow in your beer.)
