My girl has recently been mated and bled continously from day 1 to day 39, she is just at 4 weeks (if concieved) dont know if she is pregnant or not yet though, she has been happy normal self all the way through, though the last 2 mornings has picked at her breakfast, i was sure she had missed due to the bleeding, but now with her being picky and sleeping ALL the time i may be wrong, another couple of weeks should tell me.
hope you have success and good luck
