For the first time ever

I ovulated on cd 17(today) because I got a positive yesterday which I know is normal for a lot of people but definitely not me! I usually ovulate cd 26ish. I wasn’t even using opk’s quite yet, but noticed the ew cm and then checked cervix and I was like what the heck? Buttttt was just wondering is it okay for ovulation to jump by 10 days? Anyone ever have a big jump like that?
