I misread my calendar and removed Nuvaring a week early (on Sunday 8/2). I had unprotected sex Monday night (8/3). I realized my mistake the next day (8/4) and took Plan B. Is it possible that I had already ovulated? I know if I take Nuvaring out before week 3, I'm not protected. I have had light spotting but no period as of today, (8/7). I know I'm supposed to reinsert the ring within 7 days, so I will on Sunday 8/9. I'm just very worried that I got pregnant.
