You are so optimistic. All those failures and you never gave up. I can say that you very patient. If it could be me I could have gone for other means. Like have you ever thought of trying surrogacy? It might be expensive but at the end of the day it is orth. Since you have been facing several miscarriages. To add on that we have the blocked fallopian tubes. Why don’t you try to solve the situation with a different approach. That way it will not only save you money but time. I feel it is high time you move on to another approach. Trying the same method over and over again with no positive results will not help. Anyway, the decision lies on you. You can find a professional to give you details on how to prevent future loss. I am sorry for what you have been through though.
