Oh sweetie, I'm so sorry they didn't give you any answers, I am certain we are going to have similar discussions with Ethan's doctor. On the positive side you probably have the same very small percentage chance that this would happen again, there is no reason that you can't have a healthy baby in the future. It sounds as though they will make a plan for your next pregnancy and hopefully this will prevent any potential issues. My midwife has told me to come and see her when we are thinking of TTC again and we will make a plan. She said I can also see consultant and decide a plan of action that I am happy with. There just isn't enough research into this sort of thing, me and my hubby have been talking about raising money for Hydrops Fetalis research as the non-immune type that Ethan had is such a mystery. There is so little awareness around this and I feel it's sort of out calling to try and make people aware of this! The causes of Hydrops run into the hundreds and there still is a huge percentage that go undiagnosed.
Big hugs to you lovely, you will have a beautiful healthy baby in your arms by next year I am sure of it xxxx
