So confused with these OPK tests- please help 😳

Jessica

So I took an ovulation test this morning. I was beginning a new box. Mind you the last 6 days I got flashing smiley. Today NOTHING. I’m like wait how did that disappear. So because I needed closure and answers 😂 I just took another and put it in the dispenser from the kit I just finished yesterday and now it’s back to flashing! Then my husband is like this makes no sense. So I peed again and put one in old and one in new dispenser. Got a circle on the new dispenser and a flashing smiley again from yesterday’s kit!!! WHAT IS HAPPENING?! What do I believe?! Help pleaseeeee :)
