BBT Advice

Madison
Hey ladies!
So I just started taking my BBT this morning. This is my first time trying it. I have two apps for fertility tracking; glow and Ovia. They both predict my ovulation at different times by a couple days off. So, I'm sorta confused on when to exactly start baby making and when my fertile week exactly is. I took my bbt this morning before I got up and it read 96.1. Glow then notified me that bbt usually dips before ovulation. How soon before ovulation though? I feel like that's kinda low temperature? Any thoughts or advice?
Thanks 🙂
