1.Hi, I have a question about the preservation of the effectiveness of contraceptive pills Vines. On Friday I took the pill half an hour earlier than usual (it was the 20th active tablet), on Saturday I took it at a fixed time -10:30. On Sundays (22 active) I took the tablet at 9 (1.5 hours earlier) because I did not have the opportunity to take it at a fixed time. Tomorrow, unfortunately, but I will also not be able to take the tablet at a fixed time and I will take it at 9 (23 active). On Tuesday, he plans to take the pill at a fixed time (10:30, 24 active) and then take the placebo pills. Does such use of tablets reduce their protection? Will relations be secured? Can temporal deviations affect withdrawal bleeding? 2. I was advised by my doctor to drink cholesterol-lowering herbal teas. Can herbal teas reduce the effectiveness of birth control pills? Is there any tea that I can easily combine with tablets (with a distance of 4 hours from taking)? I have minimally elevated cholesterol, so I got such a recommendation.
