If you have just started your fishless cycling two weeks ago without any bacteria seeding, then it is completely normal to have 0 change at this point. The first time I have ever done fishless cycling took about a month to see nitrite. I was starting to ask the same question at 2 and half weeks on various forums if it was normal. There is nothing to worry about. Just be patient and you will eventually see nitrite.
You need to stop adding any more ammonia. It is already at quite high level. When ammonia concentration is way too high, it can be toxic to even the bacteria feeding on them. So do not add any more ammonia until you start to see it is dropping and when nitrite start to increase.
I learned from first hand experience that the fishless cycling can take up to 6 to 8 weeks to complete if you do not seed bacteria from the beginning.
