Bbt chart flat, progesterone level tested on cd21 was 9.7ng/ml, also i had a lh surge in cd9, was there an ovulation? any risk of weak implantation?

Doubt Ovulation...: Your BBT and Progesterone indicate that you probably didn't ovulate. The Progesterone level should be over 10 if you ovulate and your BBT should show a temperature rise. Cycle day 9 is pretty early to surge, though not impossible. If you really are surging on CD 9, you may need to adjust when you get the Progesterone level done. Check a pregnancy test around cycle day 30 if no period.
