well they do typically pop out little tiny rounded leaves sometimes
pull it off and inspect it
you say bublish, its hard to see from the pic, its looks like a little tiny dark green leaf that is curling back down towards the bud
if the calyx have seeds in them you will see that by how big they are and some will split
male flowers growing on buds tend to look yellow in parts like tiny bananas
or hang in little clusters rather than a singular growth
it is unlikely you would just spot 1 of them, i think your plant is fine
from the pic you have posted
peace
