Prolapsed uterus- Nervous I will not be able to conceive again :(

Looking for words of encouragement. I have a prolapse of some kind and by the looks/symptoms it's a uterine prolapse stage 3. I have an appointment with my OBGYN tomorrow to determine. We were hoping to have a large family of 6+ children. We currently have 2 boys and have been trying for #3. I'm just so emotional and scared right now. Has anyone been through this or know of someone who has? Thanks in advance.
