Thanks Sandee i hope your are right!!!! I always love it when it starts springing into action. My smile was a mile wide when it first showed my ovulation, i was so excited!!! Normally a high shows for a day or maybe 2 and OV shows for a good 48 hours so you should be wel in the clear. I think the instructions state that its 12 - 36 after you get the OV that you ovulate, im not 100% though as I cant remember! Good luck xxx
