TTC with pcos wondering how i can stay pregnant this second time around.

Amie • 28, married since 2014 and trying for my second child. Have one tall healthy 5 year old boy.
I am 28 years old and was diagnosed with pcos..so I got on clomid and got pregnant I was 4 weeks and lost it. Now my Dr says we can try again...she gave me clomid again and I'm having my period now, on my own. She gave me provera but I'm having a period so I won't be taking that just the clomid on cycle day 5. I am scared though that I will have another miscarriage. Any advice or success stories? Please I need support.
