Do pineapples stop your period ?

So recently this app has been perfectly on track when telling me my period is about to come on. Normally 2 days b4 my period I’ll get signs like discharge or headaches and cramps but this time I haven’t . And I was thinking why haven’t I had any signs yet and I realized that I had been eating pineapples everyday for the pass 10 days literally ! Not purposely at all just happened to be that way ?! But anyway why do y’all think I haven’t gotten my period ? And no I haven’t did anything in months so what could it be ? My period has never been late !
