Hi, I get my periods regularly on 15, 16, 17, 18 of every month. I got my periods this month regularly. I have two marriages to be attended on 14, 15 November and 11, 12 December. I want to delay my period for November. I want it after 17 November and similarly I don't want it in December because I will be occupied with activities and holidays after the wedding in December too. I don't want the periods in December. I want to know which medicine do I take and how to take and the side effects if any. Kindly explain in detail. Thanking you.
