I may have roasted my beloved's X5!

[X5only]

I did one extremely stupid thing this morning while changing engine oil on my '05 4.4 X5- I started her up before confirming the oil filter canister was properly screwed in. As soon as I started her up after filling her with fresh fluid and filter, she pucked all the oil on my garage floor! Unfortunately I didn't switch her off immediately when I heard some weired sounds while I was wondering what the heck was that sound.

I believe she ran for a minute or two without oil having circulated into the engine system. I refilled her again making sure the oil canister was sitted properly and screwed in all the way. I test drove her the whole day today and she seems to be happy. But my main fear is that i saw some metal chippings in the oil she had puked. I haven't yet told my wife about it as I'll get my ass roasted in ultra heat! It's her car even though it was my gift to her and she's been warning me not to do anythng on her car although I've fixed many issues on my BMW 5 series.

Am I sitting on a timebomb and, as Mr Crabs would say, should be having a sinking feeling in the pit of me wallet ( read new engine)? What would be the first sign of trouble with the car? What should I expect? I'm planning to drain and refill with new filter ater a couple of days- those metal chipings I saw send shivers down my spine!
