Ok so hear me out, this is going to be sort of difficult to explain?

Sometimes I clean out my belly button and white stuff comes out that smells similar to the smell of my vagina if I don't shower for a day... I just did it tonight, and that came out as well as hair. This really grosses me out and I don't know what it is or how to prevent it. I would really appreciate any help or advice. Thank you :(

Edit: I forgot to add that after trying to clean it the second time there was something dark like blood but idk if that's really what it was
