What should I do?

Looking for some advice/experiences. I’ve previously been to the GP who has tested my hormone levels, my cortisol levels were fine amongst others, but I have very high androgen levels (basically testosterone!) and they said that this is a key thing they look for when diagnosing PCOS. I of course have all of the symptoms, excessive hair, irregular periods, acne etc. I then went for an ultrasound which confirmed I do have some follicles/cysts on my ovaries. Now the aim here isn’t necessarily to manage these symptoms, sure they probably need to be managed but my main goal is to conceive. I did manage to conceive my little boy, who is now 3, previously. I had been trying to conceive for 4 years with no luck, but I worked really hard over 2 years and managed to lose just over 3 stone. After losing the weight and 6 years since starting TTC, I conceived within a few months of my period coming back which I account to my periods becoming regular after losing the weight. Now trying for baby number 2, I have had 1 ‘period’ within the last 3 years since having my boy, so they are by no means regular thus, I am not ovulating, The GP has recommended I start taking Progesterone, which will aim to mimic a period but won’t necessarily mean I ovulate. Moreso, it aids with the shedding of the wall inside which will overall benefit the health of my ovaries. She did mention the pill, but I felt since I am TTC, this wasn’t the best bet. She also then said we could try Metformin, but she is more inclined to go with Progesterone first. I have seen success stories RE Metformin in aiding ovulation, which of course is key here. I am worried if I am put on Progesterone first, it’s going to solve the issued of my missing periods but will not allow me to ovulate and conceive, in comparison to Metformin. Any ideas with what you think I should do? Any success stories or own experiences? Much appreciated 😊
