Stuck in signing in to my yahoo account

Hello, 
I am stuck in signing in to my yahoo account. 
I know my password and email address but I have no access to my recovery email and contact number and also i dont remember the answers of my secret questions. 
Now when I m signing in, it is asking for alternate email, recovery contact or security question, i cant answer any of these but i know my password but its not asking for password not in laptop nor in cellphone. 
I need to login my email soon, its very important. 
What can I do now? Help me out ASAP plz
