flushing while on birth control

Hi! I'm just curious as to how doing a flush might affect other medications. I currently use both the birth control pill and an SSRI (anti-depressant) for anxiety. I also take various natural vitamins and supplements. On the day that I flush, should I just take everything in the morning, before I drink the oil and juice mix? I'm mainly concerned about the birth control. Will doing the flush render it ineffective? I definitely can't afford to risk that! Please let me know if anyone has any information/advice. Thanks!
