Day of 1st IUI - positive OPK?

Sara
Today is the day I've been waiting for! I took clomid CD5-CD9. I went in for a Sono on CD11, doctor saw two follicles, one on each side. I took my trigger shot yesterday at 2pm, which was CD12. I took OPK CD11 and CD12 and barely even saw a test line. Last night I took a test at 9:30pm, barely a test line. I seriously thought I somehow missed it, since I had had pain CD9-CD11 and then nothing on the CD12. But I took an OPK this morning at 8:20am (CD13) and there it is!! I think this is positive. It has to be, since this is the only line I have seen in the past three days!
I am scheduled for the <a href="https://glowing.com/glow-fertility-program">IUI</a> at 4pm today. My question is is this good timing for the <a href="https://glowing.com/glow-fertility-program">IUI</a>? I so want this to work! I know it sometimes takes a few tries, but I'm so excited!
