Should I be worried?

So my period is 6 days late now, but I took a test 3 days ago and it came out negative. I took a test about a week before I was supposed to get my period and that was also negative. But my period is late? I had been having unprotected sex… he pulled out. The sex happened before and after that first test. Spare me the safe sex advice pls, I know.

Another reason why my period could be late was last month I took a Plan B cuz the condom broke 😭 and I got a short period about a week after so my hormones could just be all over the place but idk.

Since the test came out negative 3 days ago, and my period is now 6 days late, should I test again in a couple days or smth? How long after missed period should the test show positive? I don’t feel any symptoms or anything. Just worried cuz where is my period.
