Question Title: Are ovulation tests and temperature graphs definitive?

Is this true?

Also, in taking basal temperature readings, is it necessary to take temperature readings at precisely the same time of day, prior to getting up in the morning,...or is it okay if my temp. reading time varies (from say 7 a.m. to 9 a.m.), as long as I am taking it the moment I wake up (before I move or get out of bed)?

Finally, my temperature graph drops from around 98.2 to around 97.7 on or about Day 14, then it rises back to 98.2/98.4. Then, it returns to 97.7 (plus or minus 0.1 degrees) within 3-7 days. After rising again, it then dips back to the high-mid 97 degree range later in my cycle. This leads me to my question, is it possible to ovulate more than once per cycle?

Dear Kathryn:
In any given menstrual cycle, a woman may have an LH surge and fail to release the egg. This is named "Trapped Egg Syndrome". However, almost no woman does this in most months. Thus, although this is a real entity and although it is widely discussed, it plays an insignificant role in infertility.

A basal body temperature is taken when one first awakens. Within a couple of hours, the temperatures will be valid.
Absolute temperatures have little meaning: it is the pattern that is important. The variations you are describing are the random swings in temperature that occur from day to day. The overall pattern of temperatures that are approximately 0.5 degrees higher in the second half of cycle shows ovulation. A rise on one or two days before the shift or a drop for one or two days after the shift has no meaning.
