Is this a sac or calyx?

Currently in week 2.5 of flower and here are the close up pics. All pics are from the same plant.

I'm hoping pic 2 isn't a sac... pic 3 clearly looks like pistil hairs. Just hoping pic 2 doesn't show my plant is a hermie.

i have got the same problem man and ya pic 3 female pic 2 definit sac you can tell just by the long stem

2nd pic male 3rd is fem.
