Have got a holder from an opened box and did have three tests left so only used two tests as had a day of low and skipped straight to peak with hindsight should have started testing earlier in my cycle but just followed the instructions and went with them, my last three cycles have varied by a few days and this has been since my last two missed miscarriages so that is why I was unsure of what day to start testing, this is the first cycle back using the ovulation tests. I do have a new back of tests and don't know whether I should start using the new holder for the next cycle? X
