PCOS and first pregnancy

Tina
Hello, 
I am 5-6 weeks preg and it is my first pregnancy.
I was diagnosed with PCOS and prescribed femara.
Got pregnant my first cycle.
When docs checked my hcg and progesterone last week they were happy with the levels, so I am assuming that's why they didn't prescribe progesterone or metformin. 
But now I am freaked out by the miscarriage rates for those with PCOS, and am hoping I can hear some positive stories of healthy pregnancies and PCOS w/o metformin.
Thanks ladies!
