It's been 16 days, and our perrenial rye seed will not sprout. It's been unseasonably rainy and cold, and maybe this is the reason?

We dug up all weeds in our lawn, air-rated and loosened, added top soil and mixed in...then per instructions on the grass seed, we added seed all over (no raking in) and then put a light fertilizer on the top.

What did I miss? Is it the environment? Too much rain? Is the fertilizer the problem? Should I reseed and rake in this time, or give it another week to grow?

Any help will be much appreciated!
