[|AI|]  Hi. Thanks for asking in Chat Doctor. All OCS contain hormones and will result in hormonal imbalance by interfering with the existing hormonal status of the body. So depending upon the individuals, it will take some time, usually 3 to 6 months, for establishment of the regular cyclical pattern of menstruation. One of the main side effects of the pills is irregular bleeding and bleeding between periods. Your nausea, cramping and irritability are due to the action of progesterone in the pill. You should complete all the pills in the pack and should not stop if the bleeding starts. Mistaking the bleeding/spotting before the completion of the pack and stopping the pills will interfere with the next cycle and will also abolish the contraceptive effect of the pills.
