I have been doing a basal temperature chart this month using the chart at the back of "Taking charge of your fertility' book by Toni Weschler. The chart starts at 97F but when i take my readings on a digital thermometer they are sometimes 96.7F etc and I cant even enter them on to the chart. I am not sure why my temperature is lower than average. Also I had a positive result on my ovulation pee stick and after this I have been taking progesterone pesseries (as recommended by a Dr) and my 'after ovulation' temp is only 97.6. I am confused and worried something may be wrong? Does anyone know?
