Could there be a chance?

So my cycles are always irregular. Not reason as to why either. But I ovulated apparently on CD50.

Had sex on the 5th & 8th. Had my first peak on the 7th and 2nd peak on the 8th. By the 9th AND today, my LH tests were faint and super negative.

I know you’re supposed to do it the day before, day of and day after but we been so busy. And tired due to his job. Could there be a chance of pregnancy? On the 7th and 8th, I had sticky and stretchy CM. After the deed each time, laid with my legs up for 15 mins.
