Is this a triphasic BBT chart?

Carol

I am 12 Dpo.. took dollar store HPT this am and it was a BFN :(

Compared to last month my chart is WAY DIFFERENT.

I have nausea, diarrhea, dizziness, sore breasts.

Do you think its too early to test yet?

Triphasic usually reflects pregnancy.... but am i reading too much into my temps? Im driving myself crazy.

First chart is this cycle

Second chart is last cycle
