Yes and No. Studies have been done with the newer technology and the data seems to hold. The original studies were done with transad½ominal ultrasound which usually detects a fetal heart by 6 weeks. The vaginal probe only improves that by 3-5 days.

Also, he continued to say that there were studies showing that the rate of recurrent SAB was increased if conception occurred in less than 4 months after the loss. I haven't seen those studies?????????? He didn't say where they were either.
