Cysts covering ovaries and PCOS

I have been diagnosed with PCOS, when I was trying to conceive, my doctors told me that I may have a hard time. 3 months after going off of birth control, I got pregnant! My husband and I are so thankful for our healthy, beautiful son! We have always wanted at least one more and now I am having trouble because I have large cysts (6 and 8 cm) over my ovaries.
I am supposed to have a surgery to have them removed and my doctor is telling me that if he can't get my cysts to stop bleeding during the surgery, he may have to remove my ovaries. I am so scared because I feel like my chances of a bigger family are going to be taken away! I am just hoping that everything goes well and we can have as many children as we desire! I am wondering if other women have been in my same situation and what the outcome of their experiences were.
