You get a pop-up right after your roll saying if you'd like to use the ticket. From there, the expiration date is clear. If you didn't even go to the exchange shop between now and then, yeah, it's pretty much your fault. Newer player or not, the game took the steps to lead you to the exchange shop at least once, and just about everything has an expiration date there.
