HCG and Ultrasound don’t match after Ovidrel

Aimie

I triggered December 29th after a round of Letrozole. I went in for a 7 week ultrasound and the doctor says I’m only measuring at 5 weeks 2 days. I had my HcG checked and it’s greater than 14,000. They are sending me to a high risk for a repeat US in the next couple of days. Has anyone else had a similar situation with trigger injection?
