Fertile mucous in infertile period? TMI

So I was meant to ovulate on sunday just gone. And I had eggwhite cm bout medium around those 2 days. It's not Wednesday night and my fertile window was meant to end yesterday. I got the usual infertile creamy mucus yesterday and all day. But just tonight I got 2 lots of super thick heavy eggwhite cm. one looked a tiny bit like it may have had spotting (very feint tinge) is it possible that i ovulated late and ovulated today? Or could this be left over from the weekend and it's only just exited lol. 
I'm so confused. My partner works away every few days too so I'm sad if I missed it.
