Question!?🤔

So ladies my SO and I are trying to convince I was suppose to have my period on the 23rd of this month in 4 days late! And so far I've had cramps here and there only on my left side and have white discharge could this be a sign or no? In gonna take a test on Monday Usually I'm NEVER late and I'm not stressing about anything and I haven't been hanging with any other girls for my cycle to change...
