What level of progesterone confirms ovulation?
Ovulation can be confirmed AFTER it has occurred by testing estrogen and progesterone hormone levels. If your progesterone level is high (above 4 ng/ml) this confirms that you have indeed ovulated and entered the luteal phase, the second half of the menstrual cycle.
When should I start checking for ovulation with progesterone?

What should progesterone be 2 days before ovulation?
Before ovulation, progesterone is well below 10ng/ml and after ovulation, it is well above 10ng/ml.
How many days after ovulation does progesterone increase?
During the luteal phase, the body produces more progesterone, which is a hormone that helps sustain an early pregnancy. The levels of progesterone peak at 6–8 days after ovulation, even when a woman does not become pregnant.
How many days after ovulation should I take progesterone?

In a natural ovulation cycel, progesterone rises just before ovulation, and causes changes in the lining of the uterus (the endometrial lining). This allows an embryo to implant in the uterus.
Does progesterone affect HCG levels?
In this study, high levels of progesterone did not significantly affect blastulation rates and embryo quality on the day of HCG administration. Other authors reported that high progesterone levels on the day of HCG administration were more frequently observed in women with recurring IVF failure (Liu et al., 2013).
Can you have low progesterone and still ovulate?
Progesterone may be low if ovulation is not occurring regularly (or at all), or if your body can not build enough progesterone. Some signs and symptoms of low progesterone include: Long or heavy periods. Spotting before your period.
