Progesterone intake in case of PCOS: answers the expert

Good morning doctor, I am writing to have some clarifications regarding the intake of progesterone before ovulation . In July of this year I was diagnosed with pcos only with ultrasound control, as I am trying to get pregnant I was prescribed inofert.

In September, as agreed, I return to the gynecologist who, however, has moved and entrusts me to a colleague who agrees with the diagnosis but only prescribes hormonal checks on the 3rd day of the cycle. All results normal (she didn’t prescribe me estrogen) except ANDROSTENEDIONE 18.8 nmol / L (int. 1-11.5) which confirms the PCos diagnosis. During the last visit at 17pm he sees a dominant follicle of 14mm and tells me that in about 4 days I will ovulate.
He prescribes progesterone ovules from 14 to 24 days to start immediately despite not having checked progesterone on 21 days because he says I certainly won’t have good values. The point is this (excuse the length): I’ve read progesterone blocks ovulation, so why did you prescribe it to me earlier? At 17 pm she sees that I haven’t ovulated but she still tells me to take it and she knows that I have a cycle that varies from 32 to 40 days and I never ovulate before 17 pm (I’ve been taking TB for 6 months), wouldn’t I risk blocking it? Excuse me but I already know that for us who suffer from pcos it is difficult to get pregnant, I don’t want to complicate things further!
Thank you for your patience and I hope to have an answer soon
Kind regards

Dear Mrs,
