ZvZ Defending hatch first vs 14/14

Ok, so I was in silver and I believe I can execute the Hatch first into baneling muta build fairly well. However as I began to play against gold and even sometimes PLATINUM players (because of course that's a fair matchup :D) I just lose each time, I feel as though either I can either don't scout and rush the baneling nest or drone scout and lose the economic advantage of a hatch first by having to defend the 14/14? Any advice?

Also if anyone is available I'd love to have someone coach me a bit of zerg general zvz macro because I'm a little unsure of where to go in the long games! Thanks anyway!
