We are planning on trying to conceive on our honeymoon, however, I am due on my period, 2 days before we fly, and they are extremely heavy, and last between 7 - 9 days. Because of the type of periods I experience, I don t want to feel restricted on my holiday, so I was wondering if there is anything I can take to stop my period for 18 days, that will not hinder conception? Many Thanks
