Dropped my 11week old 😫

I feel terrible I slipped at the top of my stairs and my 11 week old baby feel out my arms down the 7 hard wood stairs she’s cried right away and we called 911 instantly at the hospital they said no blood behind her ears she’s acting appropriately moving all her extremities no brusing under her eyes and no vomiting so they said they don’t have enough studied on early radiation for babies so no need to risk putting her in an mri/ct scan when all her symptoms are negative we followed up with pediatrician today she said the baby was fine I keep replaying it in my head it’s my first baby my husband is making me feel horrible about it
