Took home pregnancy test came back positive not sure of last period. Went to doctors had ultrasound they saw the embryo & a heartbeat but they couldn't measure the embryo, the ultrasound machine would not calculate it... is that normal? I have been feeling sick for about a month now nausea vomiting cold chills I was wondering if that was normal also. The ultra sound tech said it was really early in the pregnacy but my ob and radiologist never heard of them being able to see/hear heartbeat but not be able to take measurements .,,,
