Hey you out there!

I used half of my “travel days” for the first part of my trip. I had to come home in between for several things. Now I found the information that it is only possible to leave and enter your home country once. I would like to know if it is possible to buy an extra ticket to the borders and use my interrail pass afterwards again. May you tell me if I can do it this way? 

Regards, 

Anna-Maria :)
