I have been on Femara cycles for the past 3 months and have been monitoring the BBT as wekk. In the last 2 cycles, it went up .8 degrees after ovulation and stayed above 98.0 until I got AF. This cycle again I was trigger, but the temp rise was only about .4 degrees (aroung 97.7) and surprisingly it was above the very next day after the trigger (when it takes 36 hrs after the trigger to ovulate). I am confused and wondering if I ovulated at all. Has anyone else seen variation in BBT temp diff across cycles. Please share you experience and let me know what you think. Thanks
