You should be able to buy another test registration any time. The only problem that would come into play would be if you forced yourself to take the test (not being prepared), taking a chance that you might not pass. If that would happen, then you would have to wait the 3 months. If you are thinking of letting your current ticket expire, I would hold off registering for that exam until you are closer to ready because that would give you 6 months to change your mind or reschedule.
