Dear Minniet, I am so sorry for what you are going through... When you feel better, please check a topic in the FertilityFriends.co.uk that refers to 'Serum' (it's under International/ Greece). There is a very-very good (and affordable) clinic in Greece specialised in DE, with very high success rates, which offers advanced and personnalized checking and treatment for difficult cases with repeating implantation failures. There may be an undiscovered problem and I think you could take a look at the other ladies' experience and comments. You will be surprised to find out that there are marvelous clinics outside the US, where doctors try to do more than everything for patients and with a great of success. I tell you this from my personnal and successful experience! Just have a look on this when you feel better. Best wishes!
