So I’ve been tracking my bbt for a while now, and it’s been almost the exact same every morning. It dips right before ovulation and raises after, and has been in sync with ovulation predictions. Everything has been as expected up until the past couple of weeks. Lately it’s all over the place. I’m doing the exact same routine but now it’s super high one morning then really low the next day and I have no clue why. Anyone have any input/experience with this?
