Does it mean I am pregnant if I have a
triphasic chart pattern? Do I have to have a
triphasic chart to be pregnant?
A triphasic chart shows three levels of temperatures: pre-ovulation, post-ovulation, and then a second rise around 7-10 days after ovulation. Some women with charts that show this pattern turn out to be pregnant. But many do not. Likewise, your chart does not need to show this kind of pattern for you to be pregnant.
