Cancelled cycle

Quick question about a cancelled <a href="https://glowing.com/glow-fertility-program">IUI</a> cycle. My E2 level was high and I had ALOT of growing follicles. I’m on CD 10 and yesterday was my first day not on Follistim. My u/s yesterday my biggest was a 16mm. What are the chances I will ovulate on my own? Or will I not ovulate this cycle at all?
