Contraceptive pill and liver flush

Hi guys
I have done about 10 Liver Flushes in the last year or so. I want to continue but had to go on a contraceptive pill. Does anybody know if I can still do the flush? Will it affect the effectiveness of the pill? getting pregnant is not an option :(
Maybe I can do the flush monthly, when I am on my break of a week from the pill? Anyone knows? I know how bad they are for your body but no other methods of contraception works for me.. Tweet
