Thanks for your advice.
Still, I'm thinking that asking for an update should not hurt my chances of getting in if they want me.
Maybe it would even increase my chances by renewing my interest in working with them?
If they put me on a waitlist and wait for someone else's response, or if they are deciding between me and someone else, you're saying an email might hurt my application, but is there a chance it actually helps it?
Sorry for asking again, it's been two weeks today and still no response...
