Are There Any Side Effects Of Taking Microgynon?

Hi, may I answer your health queries right now ? Please type your query here...hi I am due to start my period in 2 weeks - same time as honeymoon. Doctor prescribed mycrogynon for 6 weeks no break to ensure I do not gave my period this month. I have only started raking it a week ago and I am worried that I could have bleeding or maybe even a period still? How effective is taking this pill without a break to stop completely one's period? Thanks
