I feel like a terrible mom😔

While I was nursing my little one (1 month old), I was also using my phone (totally regretted it ) . All of a sudden my phone slipped & landed on the side of her head. She cried for a couple secs then she stop but I just can’t stop crying & feeling bad about it. I gave her some Tylenol, put a cool rag on her head and finished nursing her now she’s taking her nap.She doesn’t have any bumps , her forehead just looks a little bit red .Has this happened to anyone else ? Is she going to be ok ? Should I call her doctor ? FTM here so I’m freaking out.
