ladies I am 50 years old and just had 2 beautiful healthy twins in september via egg donor IVF , my advice for all off you is remember this you are not spring chickens, so take it easy if you feel pain take it serious and sit down and rest lay down for hours, and tell you doctor, there is medications to stop preterm labor, do what ever it takes, quit your jobs let the house go and order out. I was so blessed but I had the best doctors and care Jones institute at EVMS in norfolk Virginia where they did the first so called test tube baby / IVF. They are great and have everything you need and are all geared up for such things, I lived in another city and had a great OB/gyn who correlated care with them Dr. Kemp. I have had my own bio kids and I can tell you the pregnancy is very different with all the hormones injections and all its not natural you know so dont treat as though it is , I almost lost them when my bodys natural process of hormones dropped lower than needed for maintaining pregnancy, i was already doing injections and all the pills to maintain it , but still my body needed more, Being a nurse I knew that blood was a terrible sigh and took action pronto, i called the docs on call and asked if I could inject myself with more hormones, although there was no evidence it would work it did and the babies where saved. read and do research and especially take care of yourself and trust your instincts, be pro active and what ever you must let nothing and no one get in you way of success.
