What’s going on?

So last November after exploration surgery I was put on the pill due to endometriosis and pcos, sense then I’ve gotten married (may 6th!) and stopped taking the pill sept 12th. I haven’t started my period sense then, I’ve been having sex and my boobs have been sore but I’ve taken pregnancy tests (7 at this point)last 2 were this weekend and all have said not pregnant. When will my period come back? Did I take the tests too early? Am I pregnant?
