Period after getting off nuvaring

Alta
Hello!
This is supposed to be my first period after stopping nuvaring. My husband and I didn't use any protection this month and I've been having pregnancy like symptoms, however, I know these symptoms can also happen when you stop birth control. My period was supposed to start 4 days ago and still no sign of it. I took two pregnancy tests last week and got BFNs. My question is, for those who used nuvaring, did your first period off of it start late? Thanks!
