1st IUI tomorrow,but with no trigger shot

Bee

Went for my 2nd bloodwork this cycle on August 3rd, and got 12 follicles on the left and 6 on the right. However, there are 3 mature eggs and all on the left. I got email from them on the 4th after MD reviewed my results, that I come for the <a href="https://glowing.com/glow-fertility-program">IUI</a> procedure tomorrow 6th, August.

My question is - isn’t that too early without a trigger shot and glo app says I am not ovulating till the 10th of August which is my CD 16. Premom app says I ovulate on the 12th of August which is my CD 18.
