Vitamin C to bring my period?

FYI- There's no chance I'm pregnant. I haven't had sex in 2 months. But I haven't gotten my period this month (I did last month). Im 3 days late. I'm going on vacation next week for Labor Day and I really need to get my period this week. Has anyone tried any remedy to bring about a period? I've heard vitamin c but idk if that's actually worked for anyone.
