Ovulation after stopping the pill

Is it possible to ovulate one week after stopping the pill??? Has it happened to anyone before? Exactly a week after I stopped my pill, i had ALOT of egg white CM, and the day before that I had discomfort in my pelvic area....so I assumed ovulation maybe. My BBT is kinda whack bc I haven't been getting good sleep the last several days and my thermometer is kinda old so I can't go by that. But has anyone ovulated that soon after stopping the pill?
