could I be ovulating sooner than what glow says?

Heather
Ok so this picture is kind of gross but glow says I'm supposed to ovulate in 3 days on the 3rd. I just took an opk test this morning and I checked my CM. I can't tell if it's actually my CM or semen from last nights fun party between me and my husband lol. But I'm pretty sure it's CM! Can I get anyone's opinion!!!
