Women who have had IUI

Had <a href="https://glowing.com/glow-fertility-program">IUI</a> in May. Today marks the end of my TWW. Took a test and it came out negative. Now my cycles are around 30 days & today is only CD 26. Is it possible that it is too early? Or after <a href="https://glowing.com/glow-fertility-program">IUI</a> & hormone meds if I was truly pregnant would I get a positive today. I am cramping & feel like I'm going to see AF any second
