I am now super confused. I took ovulation tests for 10 days this cycle... never quite got a positive, but I got an almost positive then the next day a complete negative so I counted the almost positive as my O day. I got bored during my 2WW so I decided to chart my bbt. According to the temp chart I should have ovulated almost a week later then I calculated. Which should I mark as my O day?
