Could I be ovulating this late?

E
Hey ladies! So we have been trying for baby #2 actively for 12 month (stopped bc about 2 years ago). I'm in my mid 30s so I was obviously worried if we waited too late to try for #2. So I just recently talked to my obgyn about further testing and will be doing the hsg test next cycle.
I just started using an ovulation test this cycle. And I actually had a LH surge last week. I am on cycle 22 and my period is suppose to start next week on the feb 23. To my question. Today I noticed a creamy sticky discharge. Now I'm wondering am I just now ovulating this late? Or is it just a sign of my period coming?
Any help is appreciated!
