Hi. Congratulations on your pregnancy.
I have PCOS and I have a beautiful 2 year old son. We just finished our 19th cycle of fertility treatments and are awaiting the results. I did have one m/c at 5-6 weeks at the end of May but that was not from PCOS, it was due to a low uterine lining. My dr. has reassured me that I will be pregnant again and will have more children...as many as I want he will help me have them! Thank God for benefits because it is pricey but so worth it. I've never ever heard that PCOS causes miscarriages. I wouldn't believe too much of that. If you are concerned, talk to your OB at your next appointment.
Good luck to you. Just stay calm, don't stress out and you will be just fine. You are 10 weeks now, so you're almost at the 12 week mark. I hope you have a happy and healthy pregnancy!
