I have been TTC with my husband for 7 months. My bbt has been so unusual and has been consistently declining - can anyone please help me figure out what could be wrong, or what to talk to my doctor about?

All bbt records I’ve kept linked together, with 98 and 97 degrees Fahrenheit hi-lighted across the chart: (click to expand!)

Last cycle:

3 cycles ago:

I have posted single charts before and some women have suggested that I haven’t been ovulating. I have been getting OPK peaks every month between CD 9-14, and I had bloodwork done last month. My doctor said that according to my levels, I did ovulate on my April 30-May 25 cycle (she did not indicate what my levels were numerically).

If I supposedly am ovulating, why is my bbt chart so crazy?!? Help!!!!!!!! I just want my baby 😭
