TTC cycle 1 - ovulation symptoms but no positive ovulation test

[PC15]

Hi, first time posting and first cycle trying to conceive.
I am using the clearblue ovulation sticks to track ovulation. But I'm not sure I have ovulated.

CD13 - negative ovulation test (blank circle)
CD14 - high ovulation (flashing smiley). DTD.
CD15 - flashing smiley, mucus, cramps. DTD
CD16 - flashing smiley, cramps
CD17 - flashing smiley, DTD
CD18 - flashing smiley
Cd19 - flashing smiley, DTD
CD20 - flashing smiley

As you can see, I'm in CD20 without seeing the peak, 7 days of smileys. But I had ovulation symptoms around CD15. Could I have missed my peak on the testing (I was only testing once a day until CD18)? Or have I just not ovulated this month?

If I have ovulated and missed it on testing, have I covered enough bases on the days we have DTD do you think?

Shall I stop testing now?

Not tracking temperature. My cycles range from 28-30 days.

Thanks in advance for advice

Hi wanted to come back to this thread for anyone else trying and not getting a static smiley. I must not have tested at the right time for static - because I actually got pregnant this cycle, even without getting the static smiley. So if you haven't seen a static smiley don't worry still continue to DTD!

i searched this and was wondering if you got pregnant and it so reassuring that you did! so glad you came back to update!
