Did I just get rid of my Hearthstone quests?

Two of my hearthstone quests had refresh circle-arrows or something on the upper right hand corner. I clicked on them and new quests took their place. I can't see the old quests now and I wanted to play them. Did I just get rid of my hearthstone quests and is there any way to get them back?

Unfortunately, you cannot get back your previous quest, but you should still have the same number of quests.

The button in the top right corner corner is a “reroll” button which replaces that one quest with a new randomly-chosen quest. You can only use it once per day.

The main use for the reroll button is if

• You don't want to attempt a quest (for example, it has a class you don't want to play).
• You'd like to take a chance on getting a quest with a higher gold reward. (This may be obsolete with the November 2019 patch which changes the quest list and reroll behavior; I'm not sure.)
