45 days of mystery bleeding and weird BBT

I'm new to interpreting bbt. 7 months ttc and getting frustrated and discouraged by how my body has been responding to quitting BC.

I had several days of flashing/high opk, and peak opk July 18. That same day I started noticing pink when wiping. Today July 21 had bloody discharge.

This is followed by 45 days straight of having bleeding, a combination of my period, spotting, and bloody discharge, that finally stopped July 11. Yes, I have been to the doctor several times. They have done various blood tests, swab test, and tansabdominal transvaginal ultrasound. The only thing found was a yeast infection which I was given medicine for, but my doctor did not believe was the source of my bleeding.

Doctors don't know what is going on. The current recommendation is to wait. I welcome any insight. I went off of homromal BC pills in January after almost 3 years.

I took temp at normal time, but woke up and went to bathroom in the middle of the night, so this was after 3 hours sleep.
