Will I be charged after my 7 day premium trial on spotify?

I have an iPhone 6 and recently downloaded spotify, so then a message appeared asking me if I wanted to try it 7 days and I said yes. I'm kinda worried about this cuz I have my credit card payment method on my iPhone so I don't know if it's gonna charge after the trial ends. Btw, I don't have any options to cancel subscription on my account, it just says "subscribe" so I don't know if I'm subscribed or no, or if it's gonna charge or no.

No, you will not get charged for this.

If you didn't type in your credit card info, then it's not going to charge you.
