Im not sure but i think if you were too cut them they would just grow back as bangs again. The best bet i think would be to let them grow out and if they are are rlly annoying just get clips and pin them back. :)
im thinkin you can most definately do whatever you want when you want so cut your bangs have fun =) go at it ha
Is there any particular reason you're not? Because otherwise, you can cut them whenever you like..
