Baby measuring smaller than expected

Jen

I went in for my first scan that should be 8w1d, the ultrasound measured the baby at 6w1d with a heart rate of 90bpm. The nurse didn’t seem very optimistic. I will go back next week to see if there is any growth. Has this happened to anyone else? 2 weeks seems like a lot of time to be off by. I had a miscarriage in April at 9 weeks. It’s going to be so hard to go through it again.
