My belly button- scabbing

Ke

Sorry if TMI! Bit of a random one.

I have a deep innie belly button. I noticed a strange hard little lump/bump in it earlier this week and on Friday when I investigated again I noticed there is now a scab inside (in the middle). It’s still there today, Sunday.

I haven’t picked at it or anything like that.

Anyone have anything similar or know if this is pregnancy related?
