Unsure

So on October 21st my husband and I had unprotected sex (we were super drunk) I know he didn’t cum but that doesn’t mean much. My period was suppose to start on the 1st of November. But it never did and I never had the usual signs of PMS ( acne, sore boobs, bloating). It’s now the 7th of November and no such lucky. I’ve taken 2 tests that have come up negative. I took one on the 2nd and then another one today. But still nothing. Should I be worried? Should I wait a few more days and test again? Or just assume that I just have a missed period and go on with my life (it’s also important to note that I am always on time. And I have been for years. So missing one or being this late is very unusual)
