Dh and I found ourselves in this situation when pregnant with ds2.
Following the nuchal scan we were advised our child was high risk of; Downs syndrome, Trisomy 13 Patua syndrome and Trisomy 18 Edwards syndrome.
A short definition of trisomy 13 and 18 means baby would have severe mental retardation and many physical birth defects, organ failure and most babies die before their first birthday. (losing a baby after birth was more heartbreaking for us to think about than it happening whilst I was pregnant)
We had talked previously what we would do if we were faced with this and the decision was mutual that we would terminate.
The 2 weeks following the biopsy were the worst of our lives, I shed so many tears, I was a mess. We went to church every day and prayed our baby was spared of these syndromes. Our thoughts were still to terminate if baby did have any 3 of these syndromes.
In our opinion if our baby wasn't healthy to enjoy quality of life it wouldn't be fair to bring him into the world. We also took into account the financial pressure, hospital trips and the life of struggle we may have had ahead of us and decided it also wouldn't be fair on us.
Thankfully our baby boys results came back clear, we were overjoyed and relieved. Connor is now 8mths old.
Until your actually in the situation you don't know how you would would feel or what you would do.
