Late ovulation past period due?

Has anyone ever ovulated very late? My cycles are supposed to be around 26-28 days I'm assuming but I am now on cycle day 31 with no sign of it coming. I have taken pregnancy test for the past week with all stark white negatives. Today I have had a gush of watery and stretchy egg white discharge which is now confusing me if I am just somehow ovulating super late. Any similar experiences?? What did it turn out for you? No symptoms really. I have felt nauseous and have a sensitive tummy every now and then but it's very mild so I wouldn't even but some thought into it meaning anything lol
