Dropped baby. Please help.

I fell asleep rocking my baby to sleep. She's almost 7 weeks old. I dropped her when I fell asleep. Please don't judge me as I haven't slept much since before I gave birth. She fell on hardwood floor. I picked her up from her crying and she stopped about 1 minute later. No bumps.. no swelling.. no blood. She fell back asleep and I woke her up twice to check on her within the hour and she seems normal. Should I freak out? Has anyone else done this? Is her skull ok from her soft spots? Should we go to ER? From what I read it says not to go unless something is bleeding or broken. Advice?
