No trigger shot

Lindsay
Hello, 
Did my first <a href="https://glowing.com/glow-fertility-program">IUI</a> two solid days ago and didn't have a trigger shot. I did get an ultrasound and had two healthy follicles.
Is this normal? Has anyone had success with an <a href="https://glowing.com/glow-fertility-program">IUI</a> without a trigger shot?
