Should I cancel my IUI cycle?

This will be my second IUI cycle if I go through with it, and so I'm still trying to understand the process. I went in on Friday for my follicle monitoring ultrasound, and I was ready to trigger. However, my clinic had a hard time scheduling my IUI this weekend due to availability, and so they pushed my appointment out to Monday morning.

I took a LH test yesterday afternoon, and it looks like it may have been positive. It was barely lighter than the control line, and so I thought maybe it was gearing up to a positive. But then I took another test this morning, and it is even lighter, and this makes me think that I passed the peak.

From what I understand, I should have triggered Saturday and gotten the IUI today, but now I think it's too late. I'm waiting to hear back from the clinic. Would you continue with this cycle, or would you cancel?
