HI I Am 26 Years Old And Getting Married On

HI I am 26 years old and getting married on 23rd march. I got my periods on 24th feb night. I want to be tension free and relaxed for my wedding so need to prepone my periods so that it starts at most by 18th or 19th march. I am regular in my cycle and usually get my periods 3-4 days before. But to be risk free and sure, i need help in this issue. Also i tried postponing them this time by having coriander seeds in water thrice a day, as I read it induces cooling, but i got my periods around 6 days before the 30 day cycle date. This time i cannot take risk as it is my big day coming up. Please suggest any medicine/ natural ways whichever is best to prepone my periods.
