Which BC pills is effective to stop periods and doesn't cause break through bleeding??

No Such Thing. There is no guarantee that a birth control pill will not give rise to breakthrough bleeding. It is your hormone and body profile and metabolism and the interaction with the pill that are variables. Most birth control pills are available world wide. Levora (ethinyl estradiol and levonorgestrel) and Levlen is available in India and will work well to delay your period. Please discuss with your doctor who knows you well.
