Baby doesn't cry tears?

C
So I have a 9 week old & I have yet to see him shed a tear when he cries. I read online that by 2 months at the latest they will start producing tears. It also said it could be clogged tear ducts, but that he would have a yellow discharge & he doesn't at all. Anybody else experience this? FTM so I'm a little lost on this
