Fallback temp?

Kate
Anyone ever experience a "fall back temp?" I never have and have been charting for over a year. My normal cover line is between 98.1-98.2 (I used to use Fertility Friend but this is my first month using glow). I have been getting acupuncture for almost 3 months and this is my first month taking Chinese herbs. Thanks in advance for any advice/stories shared! 💕
