Hello Manitz, I hope that you are home and taking care of yourself. I was in the same position as you in may of this year and hope it helps to know I made the same decision. Like yours, my baby had worsening hydrops, and like you, whist it was difficult to understand the advice about the significance of this, we felt it was a sign that our baby was struggling and may not make it to full term. We had long discussions about what life would be like with a child with Down's Syndrome, but at the end of the day decided that was immaterial as we both instinctively felt that our baby would not make it.
I also strongly felt that I needed to spend the rest of my pregnancy bonding with my baby to comes to terms with the DS diagnosis; but I could only protect myself against the heartache of a late miscarriage / stillbirth by not bonding with my baby (after 3 early miscarriages I am pretty good at that in the early stages). The other factor was that I did not want my 4 year old to have to experience the death of a sibling.
I honestly do not know what I would have done if we got the DS diagnosis without hydrops. I have learned that until you are in that situation, you do not know how you will deal with it. I always thought that I would not have a CVS, but there was no hesitation; my baby had something wrong and I needed to know what.
At the time, I felt that I would not want to try again, but I felt re-assured by the advice I was given about future risks and am tentatively back on the TTC roundabout.
I wish you and your family all the best x
