I just started charting my BBT over the last month and my chart does this interesting thing:
97.3 (average) prior to O
97.7 (average) for 7 days following O
98.0 for the last 3 mornings.
My temps only fluctuate by .1 of a degree up or down, but most of them fall on the average I have listed. My chart is very clearly triphasic, but I've read that one shouldn't rely upon a triphasic chart to indicate pregnancy. I'm not holding my breath, or anything, but I wanted to know what you ladies with some BBT experience think. TIA, shaylind
