Singout of all devices. You can do that by going to your Gmail. In the buttom right you will see the number of devices that are currently logged in. Hit details and sign out all sessions.

If someone are using your account they will be prompted with a login screen.
I'll suggest changing your password before doing this.

Is it willing to give you the locations of the devices?
