going crazy

Ugh I should be excited about sitting at the doctors office and waiting for my IUI to be done, however, I dread it. This is my 5th IUI and I'm getting sick of it and a bit discouraged. I will add there's no clomid involved, I ovulate on my own. I did however, trigger yesterday because I'm parainoid about timing, but guess what? I'm still paranoid about the timing. My scan was yesterday and supposed to trigger last night and come for an iui on Monday (36 hrs later), however, I got a positive ovulation test before I triggered and they told to do the trigger anyway and come in today, not Monday. Honestly I don't feel like I'm about to ovulate, but Id rather be a bit early than to be late, I don't want to miss the egg. What puzzles me is that the +opk yesterday was around noon, and then around 4 pm (right before the trigger) it was negative, I thought perhaps my urine was dilulated ... Im driving myself nuts. I actually skipped my iui last month because I didn't do a scan and couldn't get a good reading on the opk tests (yes I use digital) ... 🙏🏻😩 I just hope this works !!!!
