Found out I can't have children

My husband and I have tried for 7 years to have a baby and all four of our pregnancies have ended in miscarriage. The last baby was sent for tests and we found out he was a boy with downs syndrome. We have been told that our chromosomes are not compatible and so every pregnancy will end this way. This was 5 days ago and I feel I am sinking into a dark pit. I can’t stop crying and dont even want to get out of bed. I dont know how I can pick myself up and move on.

So sorry to hear this my thoughts are with youx
