implantation cramping?

Stephanie
I had an ultrasound on 6/12 which showed 2 mature follicles on my right side, was given trigger shot and did <a href="https://glowing.com/glow-fertility-program">IUI</a> the next morning.  It's CD 19 and I'm having cramps on my left side.  Could it be implantation cramps? I guess I expected them to be on the right side,  any input would be great. I'm probably just losing my mind in this TWW
