Did I not ovulate? Or could I have missed my surge?

The darkest line I got was at cd 16 & i tested at 11:30. Then I couldn’t test intil 5:30 pm next day…could I have missed my surge in that time frame? Or did I most likely just not ovulate. The cd 16 was soooooo close to being as dark as the control line. I even had all symptoms of ovulation (sore nipples and breasts and sharp pains in only right ovary).

Feel free to zoom in to get a good look at tests and let me know your opinions. Anyone else get a line very close to positive control line but not as dark like mine & conceive???
