Cramping post hcg trigger

Joelle
I typically don't get any type of cramping, but once in while I will have some cramping across my lower abdomen right before I get my period.
I am on my first round of <a href="https://glowing.com/glow-fertility-program">IUI</a> and had the trigger shot last night at 10:30pm. I woke up this morning, and I'm feeling the same type of cramping that I do when my period comes. Has anyone else had this after the trigger? Could it be ovulation??
My insemination isn't until tomorrow morning, so I'm worried that if it is ovulation, the egg will be no good by the time of insemination!
