Help me have a baby after two miscarriage!

My name is Siera, I have had 2 miscarriage's that were exactly one year apart to the day. My first miscarriage was a tubal pregnancy where I almost lost my life and had to have emergency surgery. I lost my baby and my right tube in that surgery. Since that surgery I have gotten pregnant one other time but also lost that baby. I have been diagnosed with fertility issues and also PCOS, which combined have caused me to struggle getting pregnant. My husband and I have been trying for nearly 4 years to have a baby of our own and have had no luck. I feel that our strongest hope will be an IVF treatment.
