Can a progesterone test of 15.5 ng/ml 7 day post ovulation means the women is not entering perimenopause or other tests needed? can it occur at age 34

Ovulation occurred: If done, progesterone levels are checked on day 21 of the cycle (7 days after ovulation) to check if ovulation occurred. A structure within the egg, the corpus luteum, normally produces progesterone. Documenting ovulation does not confirm or deny perimenopause. Typically tests are not done to confirm perimeno, but irregular periods & other symptoms may suggest it. It RARELY occurs as young as 34:)
