Mad? 🐶🐶

I know this isnt "pregnancy related" but I have a 3 month old lab puppy, who is VERY attached to me. Recently, I had to be admitted to the hospital for 2 days/nights. Now that I'm home, she seems mad at me so to say. She dosent wanna cuddle, she wants to just lay on the floor away from me. She dosent wanna lick me, or be petted. Do you think she is upset with me?
