Infected Belly Button?!?!

My son lost his umbilical cord day F I V E (currently 10 days old)

I go to change his diaper just now and see this:

My heart stopped. I dabbed it with a wet wipe and there was no fresh blood, no blood on onesie or diaper either.

I change him, feed him, grab a warm Q-Tip to clean it off and:

Of course the Q-Tip had blood and I wasn’t able to remove the total crust, and I’ll monitor it

But is this infected?

Do I call doctor now?

Hello!
