Those might be male preflowers but two hairs could pop out of those and it would be female. Let them sit a little longer, you'll know its a male before it has a chance of pollinating.
Im leaning more towards female. Male preflowers are a lil more oval round. Give it a few more day it should kind of open up and two pistils should come out if its a female just give it some time keep a close eye on it just in case it is a male but I higly doubt it.
