Help! FTM scared AF!!

So i was feeding my baby that fell asleep. Shes only 10 days old and i was on the couch with her and i was less than a foot way less i think and i dosed off and dropped her! she landed on her back on the couch didnt even budge or cry. She seems fine i changed her diaper n continued to feed her after n now im scared that small but soft drop could hurt her and i dont know about it. She has full leg function still so idk someone please just calm my nerves. Im so scared i could never dose off again this was a lesson i know but help me feel okay. If there’s anything u think i should worry about let me know please no basing.
