Bleeding rat?

k ive got a breeder rat and she gave birth 3 weeks ago and doing great nursing. got in the tub today and she was bleeding from here woohoo (uno) lol
not alot but there is some residual blood down there and about 8 or nine spots in the tub. now sign of a woond it looks as if its coming from the inside. is this normal, this is my first litter of rats. never seen it with any of my mice or ASF's.

thanks

She is probably giving birth again if she wasn't separated from the male when she gave birth the first time.

If not, then it doesn't look good. Females rats don't bleed out of their vagina unless something is wrong, or they are giving birth.
