The triphasic guarantee?

Melissa • Wonderful husband and beautiful son.
So I've just realized that my chart has gone triphasic. I am new to all the terms but I am googling like a mad woman. I know women with a triphasic chart are threes times more likely to get a bfp. I really really don't want to get my hopes up. I may vomit out of nervousness. Does anyone have anymore information about triphasic charts?
