Ewcm for days?!

So I had ewcm on my predicted ovulation day, last Thursday for sure. I had creamy cm on Saturday and since then it's back to almost ewcm but not globbing. More mucus-like. Usually I have ewcm for one day and then back to creamy or none. Is this significant or just a normal thing? I've been ttc for four months and I never had this type cm for so many days. Is my ovulation day possibly off?? Thanks!
