Firstly,The safety profile of the drugs u are on contains telmisartan which is not safe to be taken during pregnancy , it causes fetal defects specially if u had taken it during embryogenesis period
Secondly , your age is a concern, for chromosomal anamolies risk increases with advanced maternal age
Thirdly since u were a known case of autoimmune ds if
liver which needs to be evaluated before giving a green signal for pregnancy as work load of liver increases during pregnancy and ur condition may worsen
I would suggest u to meet a geneticist and ur health care provider to help u out during this pregnancy event .
