Shading issue when adding Subdivision Modifier

Question

Firt things first, needless to say that I'm still a newbie haha.

I've been learning how to model with extruding vertex and faces, instead of starting from a cube.

Everything went pretty well until I decided to add a Subdivision Surface modifier to smooth everything and I found this(Also happens when I right click and check shade smooth):

Also I let you see the X-Ray version, which made worry:

So thanks in advance and any help would be appreciated :3

Fixed by deleting the faces and adding them again.

Hey :). In the future, you can just recalculate face orientation. Some faces are visibly flipped in your x-ray view. Good luck with your project. – jachym michal Mar 29 '20 at 15:01
