My wife and I just found out that we are having identical twins. We already have a 19 month old, so we will have 3 children under the age of 2 1/2. We have gotten pregnant through in-vitro fertilization both times and the doctor told us at our last ultrasound that we were only having one. My wife asked him if he was sure and he said he was 99% sure unless one was hiding behind the other. Sure enough, we went to his office Thursday and found out we are having twins. Not just twins, but identical twins. He said he has been doing this for 20 years and has only seen 3 cases of identical twins. We are very excited but also in a state of shock. Are my tennis playing days over?
