Yeah... I'm afraid not yet.
Triphasic basically means you have three "phases" of temps. Your temps during the first 2 weeks of your cycle (AF, etc) are one level, your thermal shift is the second level and in some cases, you'll get a third level of highs during the final week of the cycle.
Sadly they don't always signal pregnancy.
Here's a chart of mine that FF labeled as Triphasic. Notice how each bubble surrounds a grouping of temps that are higher than the previous ones.
