Hi I have been using cilest birth control pill now for 4 months, I have ran 3 packs of cilest back to back with no break because i have been vomiting on a daily basis, currently i have 5 pills left on the 3rd packet but I have had some consistent but light bleeding for the past 7 days, is this something to worry about? I have been vomiting almost every day but I was told that if I don't vomit within 3 hours of taking the pill every day which i have done the pill will still be effective?
