OPK test-1 digital, the other 2 lines

I really like the CBE digital ovulation test kit.  But $40 a pop for just a weeks worth is a lot and they say that you should test 2x a day so I bought the CBE original also (the one that does the lines).  Took the digital Mon.afternoon and had my smiley face.  Took the line one Tues morn. had 2 lines and then took the digital and original one in the afternoon (using the same cup of urine) and had the two lines on the orig. but not a smiley face on the digital.  Does anyone have any input as to why this could be?

I use the CBE and it always worked for me fine until I got on clomid. There is a toll free number on box I have called before and they could problably help you. good luck

Clomid will cause the OPK to test positive!!! so be careful... I can;t remember the amount of days you need to wait...you could probably call CBE and check with them or call your Dr. office...they should know....good luck...

Thanks ladies.  It has nothing to do w/ Clomid though.  Not on that. Took another OPK test (not the digital) this morning and had -. If I need it though I will keep that in mind.  Good luck 2 u.  God Bless.
