help!!

I'm scheduled for an IUI this morning. yesterday I had several symptoms of ovulation but my opk was negative. It was darker than it had been, but not as dark as the control line. Today the opk was definitely a negative. Much lighter than yesterday. My temp jumped this morning too. Could I just have missed it on opk? i have PCOS so I know that affects the opk. I'm just freaking out.
