well yup thats is your sign for sure. kinda hard to tell right here for me, in a couple more days the read will be easier and more certain (my opinion). the fact that its round may not be good, what to look for is if a stem is connected to that new growth its growing a sack. if there is no stem and is generally wider and base and skinny pointy almost end would be female. don't throw it out i can't tell.
