Positive opk no bbt rise please help

[babyoneill]

What is going on with my chart this month? My temps are usually all over the place in my first half and even though I don't get a massive rise after ovulation I do get a small gradual one but this time I'm not getting anything and I usually get sore boobs around the time of ovulation

Please help

So annoying when you have a weird cycle. How's the battery in your thermometer?
