Minecraft username and email won't work?

I have tried logging into minecraft with my username and I have tried all 3 of the passwords I ever use so then I tried logging in with my email that I know I used for the game along with the only passwords I would ever use. None of these worked so then I tried resetting my mojang password but no matter how many times I try it doesn't send me the notification

Mojang implemented a new log in protection did you log in from a different ip. Check your email the one you associated your account with you probably have an email from them saying they thought you were hacked so they changed your ip
