hi, this might sound like a ridiculous question or not, but I was wondering if apple cider vinegar might interfere the effectiveness of birth control pills. I've been on ginet 84 for about 7 months now, and about 1 or 2 weeks ago I started drinking about 4 tablespoons of ACV daily. I know I have to avoid grapefruit and I was wondering is vinegar was a "must avoid" as well. Thank you
