What happens when I have a short surge

So a little back story I got cm VERY FERTILE on Tuesday in the afternoonish I then got an almost positive on Wednesday at 9:30. The next morning at around 6:30am I got a positive which I believe was my peak because it was my darkest one. I then tested again at 10am which was still dark but not as dark and then lastly around 7pm the same day and it was negative. So my question is does a short surge mean that I likely didn’t ovulate or does that just mean that I ovulated early like yesterday (which was the day I got the positive and negative) instead of today. Can anyone explain this to me. Also I inseminated on Wednesday night during my almost positive and then also the next day 2 times in a row between my positive and negative did I miss my surge or am I ok?

CM ON TUESDAY

ALMOST POSITIVE AT 9pm

POSITIVE THE NEXT MORNING AT 6AM

THE NEXT POSITIVE AT AROUND 2PM

I DIDN’T GET A PICTURE OF THE NEGATIVE
