If there are no males around and you are growing in a space where cross pollination is highly unlikely, chances are she polinated herself, if this is the case, CONGRATS, you produced a whole batch of purple queen feminezed seeds.
I would just keep growing her to maturity, take the seeds out carefully when they are mature and use the rest for extraction, or if you did the job by hand you can just smoke the flower.
Either way anything is better than trashing them. Unless you got some other females in the same place and don't want winds to spread the problem.
Good luck growmie.
Stay lit.
