ovulation PLEASE HELP

C
Does anyone whose gone through <a href="https://glowing.com/glow-fertility-program">IUI</a> found out that they ovulate like days before their period instead of in the middle when they thought they did?? I am hoping that's the case with me! I usually have a 28-32 day cycle and I'm on cycle day 21 with no positive test. Please comment. I'm beginning to lose hope. Thank you & baby dust to all!
