Starting ivf for baby number four

My name is Carlee, my husbands name is Nick we where blessed with two other kids from a different relationship and where blessed with one more together. We also have a baby boy together that is in heaven. We experienced infertility for five years before we got pregnant with our son we lost him at 17 weeks pregnant. Then seven months later blessed to get pregnant again with our rainbow baby girl! We have been trying to conceive for a year and half after our daughter with no luck. Last summer we found out for sure the only way we can get pregnant is ivf due to having only one tube and the tube is fully blocked. I have been to several doctors to see if we can get it unblocked with no luck.. We found an amazing ivf clinic that is decently priced in Phoenix. We would love to do ivf to have at least one more little blessing.
