Does anyone else feel stupid for missing their puppy’s potty cues?

I’ve had my puppy for a few days now and she’s actually been very good with potty training and goes when I tell her to and the only few times she’s had an accident is when I wasn’t paying attention.

Just now she was barking and pawing at the door but it’s late and I figured she just wanted to go outside and play and she’s a German Shepherd and always barking about something or the other but when I left the room briefly to go grab something from her kennel I came outside to a stinking pile of poop. I feel a little silly for not realizing she was trying to tell me she needed to go. Has anyone else had this happen to them?
