It is possible that she is scupiously clean and could have cleaned away any blood spots without you seeing them?

my lulu is very clean i didnt now when she was in season, i new she was due and kept a eye on her but everyday i checked there was no blood, it was only when she started pushing her fanny into the faces of anything that looked twice that i thought she has to be in so i put nickers on her at night with a pad in and yes in the morning there was blood on the pad but i would not have none if i hadnt of done this as she was really really clean
