Had to move a mattress and now I’m stressing

We recently got a new kitten and it ran under the bed so I just left the door open in hopes it would come out if we just left it be.. a couple of hours went by and it just started crying under there and without even thinking I lifted the mattress up (a queen mattress) and instantly felt like I did something wrong🙈 I don’t have pain but I’m really stressing out about it because I’m 6 weeks and everyone keeps telling me not to lift heavy!😞 I hope I’m just overreacting because I’m already feeling terrible🙈 do you think it could have done anything??

Thank you ladies so so much! I feel so much relief💕
