SOS,,, How can I delay my period? HELP 😥

My wedding is at the fifth of next September it's only month and few days left,

my fiancée will leave the country he worked at for 10 days, he will come at our country and marry me, then he will have to travel again for work,

My mom and my dad passed away, and my sister act like if she isn't my sister and as she is a complete stranger, so I have to plan my own wedding alone,

I have to do every single thing by myself, I need my power, focus, strength,

and it's only ten days long he will stay with me as a short honeymoon,

My period made me feel bad and sleepy and fatigued 😔

I need to delay it for only one week,

So girls could anyone please helps me?! 😥😢😰
