that looks like a pre-flower calyx to me, different strains have different shaped calyx.
If those are pistols comin from that odd shaped calyx, than no, it doesnt look to be a hermie.
at that far along , if your not seeing any clusters of "balls" anywhere, than shes a straight up girl!!
Calyx's will sometimes grow very large at the node( the point where the leave stem meets the main stalk). So you may have some seed free weed ( sensi bud) in a few more weeks.
Enjoy!!
