It sounds like you are doing everything right. Be patient with yourself, though. Lucid dreaming is an art of trial and errors and many of the experienced lucid dreamers here waited ages before all their efforts started to pay off.

Don't stress out over the WILDs. Make the efforts when you wake up during the night and try various techniques if you are getting bored or frustrated. I am starting to see WILDs work more, but it has taken me a long time to get here and it was very much worth the effort and patience.
