I love your avatar. Plumeria is one of my favorite flowers.
I have been keeping a running thread in the "review my sway" section. It's turned into more of a journal and experimenting log than anything else. I had a miscarriage in March which was the result of a practice sway (not intending to sway, but testing everything else) and since then, my husband and I have been very, very cautious about avoiding pregnancy and we're both scared to really sway or try to conceive again.
I'm doing a lot of things that aren't very girl sway friendly (working out, on a fruit/veg/protein shake diet, no carbs minus fruit, etc) because these things seem to help my testosterone to stay lower, but I'm still very symptomatic of PCOS: weight loss resistance, hirsutism, oily skin, acne, etc.
I'm taking all girl friendly supplements though because they help with PCOS. I'm also experimenting with some things that haven't totally been tired here.
I'm basically in the search to balance both testosterone and estrogen. Too much testosterone damages egg quality and estrogen can too, but one of its biggest impact is on progesterone. If there is too much or too little estrogen, progesterone levels usually aren't very good, especially not enough to sustain a pregnancy. One of my main symptoms of being progesterone deficient is soaking night sweats after ovulation, usually 7-9 days before my period starts.
Anyway, if your doctor doesn't put you on metformin at some point, I would be surprised, especially if s/he knows you will be trying to conceive and your cycles are irregular.
The thing that helped me return to normal cycles is a combination of metformin and Vitex. I was on that for the longest time before I introduced saw palmetto.
About your boys in the family question, I don't think an all boys or all girls family means the same will happen for the next generation, but if I were you, I would definitely do everything I could to have a healthy pregnancy and conceive that girl. :)
