If you have higher degree of damage, I would recommend avoiding all
oral contraceptives. You are correct, they are hard on the liver
and sometimes cause liver damage
and elevated LFTs even in healthy women. Recommendation not to take them if you have liver disease is a very sensible one.
Try other methods of birth control that don't involve hormones. They do work and work well when used correctly.
Congratulations on completing your treatment and feeling so well.
