Hello Dr., my periods are regular, they occur usually on the same date every month (around 29th) or just a day before or after. But my last 2 periods i.e., in August and September I had them 3 days before (august I had on 27th and September on 24th). My husband is coming down for holiday on October 16th and will be here until November 9th. I would like to know what contraceptive pill can I take to prevent getting pregnant and from when I have to start it. Also, I am visiting my in-laws from October 19th to October 28th (have some poojas to attend). How can I postpone my period so that I have a happy vacation. Please advice.
