How To Delay Periods?

Please someone help me....

I am getting married tomorrow ie 13th June....

I went to doctor 2 weeks back for contraceptive methods and was prescribed Femilon.I started taking it from the first day of my periods which was 6th june...and today ie 12th june is my 7th day and the bleeding has not subsided yet.
I usually dont bleed for more than 5 days.
Its my wedding tomorrow and in our religion it is considered very unholy for the girl to be in her periods on her wedding night.

I went to doctor today again and she prescribed me Trenaxa 500 and asked me to start right away.I am asked to take 3 tablets daily for 5 days...
Will this help???Its my wedding tomorrow and I am very tensed.Please help..please!!!

I am 21 yeras old!!
