I'm getting married on July 3rd (2017). We have decided to use birth control methods for 3-4 years post marriage. I would like to know more about birth control pills. My periods are regular. I got my periods on the following days the past few months: 23rd Feb, 26th Mar, 25th Apr Since the periods is closer to my wedding date, I wanted to start it a couple of months in advance, to see when I'd get it the next month. (I don't want it falling on the wedding day). Could you please suggest the medicine and its side effects if there are any? Is it available over the counter? (Or is it a prescription med?) When should I start consuming it? Is it too late to start this month?
