Letrozle/Trigger with IUI

Kadi

My husband and I have been trying ttc for 20 months now and I had my mid cycle ultrasound on Monday showing 2 follicles on the left @ 29mm & 16mm and 1 on the right at 31mm! The nurse was impressed at how well the letrozle worked. Had my trigger shot Monday afternoon and

IUI

yesterday afternoon. So far I've had pretty consistent cramping on the left side. Not sure if this is good, bad or normal. Looking for positive stories!
