No LH surge

Chart shows clearly I ovulated. Temp drop, followed by huge spike in temps.

I did not get a positive OPK tho. I tested twice a day. I usually have a progression then 2 days of very positive tests, then it lightens up. I don’t even need to test twice a day usually, but this time I had ovulation signs, so I tested again & again waiting to see my surge.

Does this mean I didn’t ovulate “well”?? Does the amount of LH have anything to do w egg quality??

Been at this over a year, never had it happen.
