Hi agajn

Hi everybody. Not sure if anybody remembers me. I have turners and I had my son in May 2016 after my 3rd transfer (one cycle produced 4 day 5 embryos). A few years before I did the cycle I saw the re who mentioned dangers in my condition with pregnancy. Everything of course checked out and I'm positive I will need to be monitored again prior to my fet for a sibling but I am more scared this time of something going wrong. I'm still nursing so it won't be til the winter/spring the earliest. Anybody else more scared for their health trying for a sibling? I guess I also fear I am trying fate again. I love my son and don't want to leave him motherless.
