probably in my head but

I have been off the ring for 2 months, took it out early August and had my period soon after that, and again in early September, I've had protected + withdrawal (won't even let him near me at all without one on) 5 times since and I'm pretty sure I'm not pregnant but my anxiety won't let it go 😭 is it possible my body is adjusting from being off the ring because before the ring my periods were long and irregular
