Whereas mine all went through to day 21, or thereabouts, with just a light discharge throuogh the third week, mated or not, we had one who started to produce a more blood coloured discharge after being mated. As she was otherwise fit and well, I didn't go to it being a pyo, much as I thought perhaps she'd not taken She had an uneventful pregnancy and gave me 9 of what were probably the best we'd ever had. So good that we kept 3 and they all came back with the others to the UK. One gained her UK Champ.
The odd smelling blood might worry me - is it worth taking her to see your vet?
