Delaying your period

I personally feel like me period comes at the wrong time but since i first started i've been tryna plan around my period. aaannddd i think i found a trick for delaying your period. i don't know if issa coincidence or actually works(knock on wood) but i drink green tea the week b4 and the week that i'm supposed to start and i think that delays it til the next week👍🏽or longer😬 i have noticed that it does cause me to kinda have an irregular period sorta not really. if y'all have any tips lemme kno cuz ur girl need sum help.

edit-obviously i do drink water to not just green tea🤦🏽‍♀️
