fertility monitor vs. temp change ?????
Sat, 09-04-2004 - 5:30pm
Anyone know what would cause the fertility monitor to read high on day 14 and now today day 15 of my cycle (also a reading of high) if my temperature readings indicate ovulation on day 9? My cycles range between 22-25 days. Is there things that can cause false readings on the monitor. They claim its 99% accurate. Any ideas would be most welcome. Thanks.
