watery cm at 4dpo (confirmed ovulation)

I'm just confused. I'm due for AF on the 31st (roughly around there) with a confirmed ovulation with opk on the 17th. I'm having very watery cm, it's not sticky or stretchy but very wet and kind of slimy. I'm not sure why, I usually dry up shortly after ovulation and cm usually becomes sticky/tacky. 🤔 I know watery is a fertility sign but does that mean I'm possibly ovulating twice in one month (is that even possible?) or should I chalk it up to my body just being weird again? 😂
