Yes. You have a 14-month period including 60 day grace period and 12-month OPT. No matter what you do, you cannot pass the 14-month or you will be out of status.
But you will have another 60-day grace period if you will NOT be seeking another status but only packing to leave US. That should be enough and it is better than H-1 visa holders since they do not have the 60-day grace period in most cases.
