BBT Insight

I had HSG on 8/1. I did 4 cycles of Femara with this cycle being a non medicated one. The past two cycles I ovulated (per OPK) CD 16/17. So when I got a peak on the clear blue digital on CD 12, I thought it was a fluke (so I waited 48 hrs and started testing again).

I thought my temp was rising so I was coming around thinking maybe I did ovulate but then this morning, I got the lowest temp. I feel like it’s too soon for an ovulation dip...

And another thing is my temp seems like it’s all over the place even though I take it at the same time every morning...

I’m relatively new to BBT.

Any insight ladies?
