New Pregnancy.

Asalamualaikum this post is for gynecologists. I have 2 pregnancies. First one being completely normal delivered healthy baby at 40weeks via c sections. Second one was miserable ., the baby had defects. She was birn a premie at 8 months via emergency c section because her heart rate was stopping . Aftr birth she was diagnosed with multiple defects and a disorder because of an extra chromosome. She passed away the second day after she was born. 1 and 1/2 passed ,, i am expecting again. I want to talk to doctir fiza ali or rukhsana tariq of what chances are there to have a normal baby. I have hypo throdism and doc heres says there is nothing to connect between the disorder and hypothyroidism . Also i have been tracking it every 3 months and the results are always goos as per my doctor. Have been taking all my supplements since planning a baby. Please help to make me stay positive. Thank you.
