I dunno much about heat cycles, bleeding etc..
But we really dont know much and if someone can automatically tell whats wrong I will want them to be my vet lol.
Google, and even this is NOT accurate. I sometimes find myself doing research to see if my dogs are sick etc, and it only causes worry and chaos.
If you are seriously worried about it, wait til monday to take her to the vet. Other wise, listen to people tell you whats wrong with her, without being a vet !
Even if they are SUPER experience, it doesnt mean jack. We really are not face to face with this dog and cant tell if something is wrong.
How does she look? How about playing?
