Please help!! My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> calendar is predicting that I’ll start my period the first day of my vacation. I don’t want to be on for the first 2 days of my vacay so....

Should i try to delay my period or try to bring it here early? (PS): keep in mind i still have to get a bikini wax before the trip & my fertile window just ends today or tomorrow

What are some remedies that actually works?
