happened to me. Dr couldn't see anything with the office ultrasound machine so I had to go to radiology where the good ones were...luckily I was able to get in the same day. turns out I was a little earlier...they measured her just over 6 weeks. but due to knowing why I ovulated Dr and I figured she was about 7 weeks at the time. she's 9 months old now. at the time I was so scared because I've had a miscarriage before and took us 6 years to get pregnant with her.
