HELP PLEASE

Kate

Hey guys I need some help! So my boyfriend is taking me with him hunting/camping this year the 29th-October 2nd. Well I was super excited about it until I realized I literally start my period the 29th and get off of it around the 3rd or 4th. I don't want to be miserable the whole time but idk what to do. Does anyone know of a way to postpone OR make my period come way earlier? WITHOUT BC.
