I'm a thin cyster too. I have no symptoms other than cystic ovaries and irregular periods. My blood work has always come back normal. I just had a baby in September!! So it's certainly possible for us thin cysters to get pregnant. I tried clomid but that didn't work. I got pregnant with the herb vitex within two months of starting it! My son is now 4 months and very healthy!
Good luck! For #2 I'm going straight to vitex again!
