If you were charting when you were trying to get pregnant, what day did you notice a triphasic pattern? We are 12 DPO, got a BFN today, but it does look like we are 3 days into a triphaisc shift. Last month I had a 14 day LP so we are not testing again until Thursday, but during the first part of the LP our temps ranged from 96.8 up to 97.2 and starting 3 days ago progressed to 97.4, 97.6, and now 98.0

When did you notice a triphasic pattern?
