text: my prom is in 2 weeks and i wanted to know how i could speed up my mestrual cycle...? my prom is april 29th and i haven't gotten my period yet! i have exactly 10 days from today until prom night!! i have to get my period! i can't take it to prom with me.. a girl at my school told me to drink vinegar and it will speed up the process i am going to try that because i am desperate! someone please help me... go to your gp as soon as possible and ask about norethisterone - it won't speed up your cycle, it will delay it. you take three tablets a day from a few days before your period is due and continue taking them until you want your period to come. hope you enjoy your prom!
