12 day old is this normal??

So while changing my daughters nappy this morning I noticed the placenta stump is slowly getting loose, this morning I noticed a little blood around it. Not much and under the black dried is pink. I’m worried I bumped it while holding her or something last night.

Is this the normal process for it fall off?

UPDATE

So while changing her nappy this afternoon it had fallen off. I had a dr appointment anyway this afternoon over the phone and I had just brought it up and she said just keep it dry it will be fine.
