Possible triphasic chart.

Bryanne • I`m 24 years old. Been together with my fiance for 6.5 years. We have a 4 year old son and TTC #2, hopefully ASAP!! Baby dust to all!!
Anybody have a bbt chart like this and ended up pregnant. Fertility friend picked it up as a triphasic chart too. I already know your temps have to stay high 18dpo. Any experiences appreciated!!
