My husband and I also tried to conceive for more than 5 years, but I have been diagnosed with the fallopian tubes obstruction. Had to do IVF with a donor egg. That helped. Now we growing our beloved son.
I think surrogacy is a good option for you. By the way, I heard that surrogacy in Europe is much cheaper than for example in the USA. Look for information on the Internet. In the clinic where we were – they did not only IVF. I personally spoke with couples who gave birth with a surrogate mother. Yes, it is not easy, but for such couples, it is the only acceptable option! Read here more about IVF: https://ivf-international.com
Good luck to you! I will pray for you!
