This may be stupid but help??

Okay I really don't know ow as much as I should,but husband and I are ttc we've been married 15 years never really prevented but haven't tried. Well long story short..AF started 23rd and ended 27th,normal for me. I went in Fri the 29th for a biopsy on my cervix. That was the 1st day over my "good days" well my last day of ovulation is the 4th I think is what it said. My thing is I am just now starting to get any CM. Could I just be ovulating late..TBH I dk if I have really ever ovulated as I don't ever recall having the CM that is described. Please tell me if this is normal. Again I am just now getting CM like this it was a little yesterday and more today??help
