HI guys
i am sooooo confused

We thought that Jazz had started her season on friday, even the stud owner confirmed it, but now i am not sure :(
On Friday she started dripping pale watery brown drips.
On Saturday NOTHING!
on Sunday (so far) NOTHING!
i have tissue tested her for the last two days and there is nothing there!
'It' looks different, although not yet swollen,
what shall i do? she was booked to go to the stud next sunday which should have been the 10th Day but there is no blood or discharge at all now, so i don't know what to do.
Please experienced breeders, i am calling on your expertise!
