You can use your Interrail pass only on 2 days in your home country (Inbound/outbound rule).
If the trip that you selected is in the future you can cancel it. If the trip is today or before, only possible to ask help via customer service:

or ask via social media for help @Interrail via private message.
The problem is that I just enter to Sweden, I don’t arrive home and I didn’t know that rule about inside country and actually I’m in te border with Denmark and it can’t be valid just for it, so that is why otherwise I should fix the travel. Anyway thanks for your answer and I’m still waiting for costumer service to answer me what I can do, because I can’t just stay so long away from home.
If you have used the outbound and inbound travel days you need to buy a normal ticket to get to you home in Sweden.
What travels on what dates have you made in Sweden so far?
