Change facebook profile pic?

[IDemiMockingjay]

Try this: Change your profile picture normally as you would. Immediately after that, go to your timeline. There will be a post saying that you have changed your profile picture. On the top right corner of that post, there will be an arrow like thing. Click it and in the drop-down list, chose "delete post". Then, no one will know
Ps- Delete the post IMMEDIATELY after you change. Or at least ONE person might see it
