My bbt is usually around 97.0-97.5 area for the past 2 weeks it has been high, 98.2-98.8 which is really odd for me. Even when I wake up "chilly" my temp is still high (I have been tracking it for over a year). The only time my temp spiked like that was when I was ovulating. My last period was 11 days early (I'm usually pretty normal-day or two late) and I tested and it was a bfn... Im just wondering if anyone else has had this or has an idea what is going on.
