Fall back rise vs estrogen surge

[Angel022605]

I've googled myself to the point of confusion. Can anyone tell me the difference between a "fall back rise" temp and an "estrogen surge" temp? Also approximately what DPO does a "fall back rise" temp normally occur, and approximately what DPO does an "estrogen surge" temp normally occur? Does anyone know? Any responses appreciated
