Low to high to low - no peak


Hi - This is the first month I haven’t had a peak on the Clear Blue tests and I’ve been doing them for 7 months. I had high for two days and then low. I test once a day (same time). I thought it might be possible to have a short surge. I had to use a new kit today btw but I can’t see how that would affect anything. Is it possible I ovulated or is this one of those odd months it didn’t happen? I don’t have PCOS.
