It is very common to miscarry a child. It is completely fine too because not every woman body can carry a child.Surrogacy is a blessing in disguise to those wishing to get a baby. It is the best solution for infertility or low sperm rate. I am glad that rather than grieving on something you can not control, you decided to do something about it. Make sure you find a clinic which is in your available budget bracket. The staff should be friendly enough to guide you through everything. Since you asked for success stories, I will share mine. After researching a lot I and my husband decided to go to a clinic in western Europe.My experience was great.The staff there was friendly and knew the language I spoke.We were also given full rights to consider about what kind of surrogate mother we want.You also seem very skeptical about the success rate. Let me tell you the clinic I consulted offers several tries in the same budget.I hope this was helpful for you and you will feel better now.
