Free 3 Month Apple Music

i was looking at the free 3 month subscription for apple music. As i was looking, i signed into my apple id and it started my free 3 month trial. I didn’t want to start it today i wanted to start it next month. so i canceled the trial 10 minutes later, now i don’t have the free 3 months anymore. i want to be able to see how this works before i spend my money. is there anyway i can get the free 3 months back?
