BBT went back up but neg test this AM. Cycle due tomorrow

L • Mom of 2 boys. MC. unexplained secondary Infertility. 3 Failed IUIs. IVF cycle started April 23.

Anyone implant late and have a successful pregnancy? does it look like ovulation on CD11 OR 12?

FF changed my ovulation date yesterday. I have had a positive test by 9DPO for 3 pregnancies. I'm 11 days past <a href="https://glowing.com/glow-fertility-program">IUI</a>. Temp turned up this morning, but no positive test. Thinking I'm out :/ cycle due tomorrow or Thursday.
