First IUI

Hi guys ❤️ I’m doing my first <a href="https://glowing.com/glow-fertility-program">IUI</a> (natural cycle and no meds). I’m supposed to go in when my opk is positive, a few hours ago it wasn’t 100% but now they look like the picture. I can go to the clinic either this afternoon or tomorrow early morning, I booked in for tomorrow as I think It might still be early if I go in this afternoon. What do you think? Worried I’ll miss my shot.
