I NEED HELP!!

Hello ladies my first prom is next Saturday on April 21st and I'm really excited until today I noticed my boobs were hurting and they looked bigger. This only happens when I'm about to start my cycle. I looked on my app today and I start my period one day before prom!!! someone please help. is there a way to make it come late or early? because I don't want to be on my period on one of the best day in my life. I don't to be in pain or be worried about getting blood on my dress on or anything. SOMEONE plz help!
