They are all different, your girl might just be late ovulator and maybe this is why she missed previously?
We were in the same situation as you are, bank holidays so tested our girl on
Friday, day 6 result 1.7(tested just to make sure she is not very early ovulator so we will not miss it testing after bank hols)
Tuesday, day 10 result 12.6
Larry said to mate on Thursday and Friday but our stud was not available on Friday...
My girl was right little Miss Floozy on Wednesday (even though in theory it might have been little early) so we let them try...
On Thursday we got a specialist to do vaginal cell cytology(sp?) just to check and that showed she had ovulated.
We had a slip mating on Wednesday and very nice tie on Thursday :).
Ultra next week, iiik!!
