Just had surgery

So just a few weeks ago I went for my annual exam & thought things would be okay. Come to find out I needed emergency surgery. Doctor said according to all the pain I was having and not being able to conceive was due to a few things. 1. My uteris had fell & was one shot from completely falling out and pulling my stomach with it. 2. I had cyst inside of the uteris as well. 3 I had a malignant cyst on my ovaries. So I went for the surgery & am now recovering. Doctor said that once I'm able to I can get pregnant again. Me & my husband have been trying for over a year. We have left it in God's hands & I have faith but really am a bit scared. Are my fears founded or am I just being silly? My husband is a bit worried for me if I do become pregnant one day. What should I do?
