Ovidrel shot, ovulate later than 36 hours ?

Am
Has anyone ovulated later then the 36 hours after taking the trigger shot? Just wondering cause I'm cramping and wondering if ovulation starts later possibly of could it be implantation? I Triggered December 24th at 11pm and <a href="https://glowing.com/glow-fertility-program">IUI</a> 26th at 10am
