how to track my iPhone 5s was stolen from Wet

There is one and only one way to track your iPhone...you must have turned on Settings > iCloud > Find My before it was stolen. Then login to your iCloud account, go to Find My Phone and IF the iPhone is turned on and connected to the internet it will show its location.

There is no other way to track it.

Apple will not get involved in trying to track the iPhone.

Report the theft to the police, change all passwords associated with accounts on the iPhone, contact the cell carrier in case they offer blacklisting.

Have you contacted the local authorities and your service provider?

And changed all passwords for services, that are enabled on your iPhone? Change your appleID password at My Apple ID > Manage your AppleID?
