I personally haven't had pcos. But my close friend did AND my sister-in-law had to use injectable meds. It took my friend quite a while to get the right balance of meds. My s-i-l took three tries....first time not enough, second time way toooooo much (13 eggs!), third time the charm! 3 eggs, 2 fertilized and she had a boy and a girl!
I'm sure the doc told you that the hormones can cause emotional highs and lows. So try to be patient and enjoy the "trying" :).
