Well after my girl decided to be a strum pet and stand for over 8 days we went for a scan last week and the scanner could see something but not 100%, been back this morning and he saw at least 4 so taking it that she was having us in for the first few days and has taken from a late mating, so chuffed as its a long planned litter, now the worrying really starts.....

That's why it's a good idea to mate until they stop standing unless you do progesterone testing to confirm ovulation.

Had you left it at first mating she probably would have missed.
