looks female to me!!! it just looks like a swollen calyx it happens at every node those were the pre-flowers. as long as there's not multiple balls together in the same spot your good. but thats just one type of hermie.
some people get bananas near the end of flower. thats just a lone male pollen sack most are not viable. but in a real male or some hermies there clustered in a pouch. and once they ripen and open your gonna get seeds every were
just so you know for future grows
she looks good to me. but some better pics will help us tell you for sure
