Difficult dangerous decision

WARNING TO ALL GIRLS ON THE PILL : I have recently gone for blood tests for a full body health check up and I went before I started taking the pill and now. The pill affects your hormones so much I am in danger as not only does it cause your body to produce too much of some hormones like cortisol (mines sitting extremely high) !but not enough of the other hormones. It also causes inflammation of the arteries significantly causing a very high risk of a heart attack. I need to stop the pill however I am starting roaccutane although my cholestrol is dangerously high , the doctor believes I don’t need roaccutane cause I don’t have severe acne but I have persistent mild acne. I’m worried about what forms of birth control I can use because the IUD has the same effect as the pill.

Are condoms safe enough ? I can’t afford to fall pregnant as I have health issues.

What else can I use to be extra careful ?

Please help !!
