i wouldnt worry about them too much.as long as your whelping box/bed is cleaned daily some do twice a day ;-)
i certainly wouldnt clean it with anything other than cotton wool ball and cooled boiled water and that would be only if it was pouring with blood and obvioulsy id apply slight pressure.
let mum do the cleaning,its best to interfere as less as u can.they should be very dry and shrivled things that fall off??
i d remember one of my pups had a very tiny bleed when i noticed her UC came away,but again i gave her to mum and said clean it and that was the last of it.
if your worried about anything call the vet.sometimes just a phone call will help settle you.x
