First of all, congratulations!!!
We definitely have a lot of similarities. First of all, I have PCOS with only slightly elevated male hormones. I don't have the classic "look" of a PCOS girl, but I also really enjoy exercise and eating well. Don't know if maybe that has helped. That being said, I do not ovulate on my own. Period. For my first LO, I used Clomid and got pregnant the first cycle. For my newest LO, I was on Metformin for a few months and got pregnant without even trying. We use NFP and it was obvious a couple months after starting that I was ovulating.
With my son, we had breastfeeding h-e-double hockey sticks for the first two months. My nipples were "too big" for him to latch around, I got terrible sores and had to exclusively pump and bottle. I never made enough milk even with Domeridone, but I never went up to the maximum dose. The Dom definitely helped and I was just happy to get him back to breast at 2 months.
I don't know if I have hypoplasmic breasts. I go back and forth from day to day. I definitely don't have the roundness that I think maybe they should have and I again have had supply issues with this LO. I am on 90 ml of Domeridone and some other herbs (that I don't know if that have made a difference). The Domeridone has made all the difference in the world. With this one, due to a series of problems, I am having to do pump and give her a chaser bottle after I BF her, but I have enough milk and actually have some in the freezer this time. Last time, I never had a drop to spare.
I was on Metformin for the first 20 weeks of my pregnancy and stopped when my doctor told me I could. I wonder if my supply out of the gate would have been better if i stayed on it? Metformin is the next step for me if the Domperidone doesn't continue to do its job for some reason.
I really hope you don't have a replay of how things went last time. The first paragraph of your post sounds exactly like what I said when I was pregnant! I don't want to say anything negative, but my one piece of advice for you is to just be prepared for what may be to come. Many people said to not believe that we were going to have problems again and just go forward confidently. I would definitely say that you should do that, but the best thing you can do is be proactive. I would get yourself set up with a great LC to start with and see her in the first few days after birth, even if things seem like they are going swimmingly. This time, I did think positively and see my LC right away and we still have had problems.
The positive is that they didn't escalate to the same level (with soreness/sores). Still working through all this, though.
Anyway, I don't have any personal experience with met in pregnancy, but just wanted to contribute my thoughts ...
