Your story makes me sad. Infertility is a very worst experience. I’m also suffering from heart disease same like you. I cannot conceive naturally. I was very depressed. Then we decided to move to Europe for surrogacy.IVF and surrogacy is the best treatment for infertility. Now I’m the mother of a cute baby boy. I think you should you with surrogacy. Surrogacy is really a blessing of medical science. I suggest you move to another clinic.who can understand yore situation. Best of luck for the future. I wish you to become a mother soon.
