Hello, I'm in the same boat, I'm starting my IVF program in a few weeks. The most important thing is to trust. To trust a clinic and it's stuff. If you trust, there is nothing to worry about I've made my choice and consider it right. I've chosen the Spanish clinic IEGRA TRES TORRES in Barcelona, because they have a guarantee pregnancy program. I've already discussed everything with my manager Elena (+44 (203) 411-45-85, Her English is fluent, there was no problem for us to talk, she answered all my questions very politely. My program starts soon, so good luck to us both)
