i wouldnt think it was her first season as you would see she was swollen in her lady area and the blood would be coming from there but to make sure wip it with a bit of loo paper. as the blood is in her poo it could be ibs or colitis, my yorkie use to have both and would have blood and mucus in her poo but it could be something much worse like parvo which has a really bad smell, if i were you i would phone the vet and tell them and then take her in asap as what ever it is the sooner its treated the better, good luck
