Can I be?

Okay so. I've been on bc for almost 3 years. (The pill) may of this year I quit taking it. And my period stopped that month from June-July. Then august it started. And after that one month it's been gone. I feel just because of stress it hasn't came back. But. Just on Monday I spotted super light pink but only when I wiped. Then Tuesday same thing. And then Wednesday it was only once when I first woke up and there hasn't been anymore. And I woke up today feeling a bit nauseated today.. Any thoughts? Or advice?
