are you open about your smells

When i get off my period sometimes for some reson towards the end ill get like this brownish left over blood mixed with my cm that has a bad smell not fisy but bad... And it smells so strong to me i wonder if me bf can smell it or is he just not saying nlthing my question is do yall try to hide the smell and keep him from that area til everythings back to normal or are yall ladies open with your man about it
