Are those Pollen sacs?

Look like just swollen calyxs to me. I have a few pic of how actual male ball sacs look and they are all clustered up.

You're looking good friend. Those are just calyxs, female preflowers. Sometimes they'll have a little wispy pistil poking out...sometimes not. But the key point is there's only 2 on each side of the stem...not a cluster of them, plus if they were male sacs they would be much more rounded than pointy like a spear tip.

i think the nub on the left is the most suspect. See 'sections' as if multipiple bits that will spread out etc.... or is that some leaf growing back? preflowers get pretty ripe and a bit odd looking at times. Since you have a bit of time, i'd let it play out longer. keep close eye on it. if it hangs like a grape, you know to remove it or the plant.

yes those are pollen sacks, pick them off and continue the grow but keep your eye out for seed, it may hermed out some how from stress or what ever reason. the seed may have a chance to hermie out, but to know 100% you would have to grow the seed out.

It can be. Have experienced many rqs strains that want to grow hermaphrodites. I take out eventually the pollen sac by hand or using tweezers if they are in the middle of a bud
