At 6-7 weeks it doesn't exactly look like much anyways so don't stress, I would get another done or ask your doctor for a better explaination
Maybe talk to your Dr about getting another ultrasound with a different technician
WOW, krissy, I can't believe a sonographer would use that word!!
I think you need to call your docs office and find out what exactly was meant by that, and ask for another sono (and sonographer)
