PAH and pregnant

Angie
I have pulmonary arterial hypertension and I am 7wks pregnant my cardiologist keeps telling me to get an abortion because there is a chance I might not make it when the baby is born... I WILL NEVER HAVE AN ABORTION! But the thought of it gets me scared I have 2 daughters as well a 17 and 3 yr old. 
Just looking for prayers and thoughts no negative comments please . Thank you
