Has anyone ever had the clear blue digital advanced ovulation tests stop working mid cycle? It says you should use the same holder from the time you start testing until it says you have reached your peak fertility so it knows your baseline of the hormones and can tell when they rise. It told me that I was high but not at peak yet so I need to keep testing until I reach peak. But yesterday and today the holder only gives me errors! I have tried testing 5 times in the last two days and the holder just doesn’t work. So frustrating. Can I get a new holder and test with that one to see when my peak is? Or am I screwed this cycle since and just won’t know when my peak is since the new holder won’t know my baseline? What do I do?

Also, I have very irregular periods, so my calendar isn’t very useful to know when I actually ovulate.
