Hi..becky.. yes you're right. doctor determines that I'm 7 weeks pregnant because of my last menstruation.. No blood test yet.. just ultrasound and pregnancy test.. thanks becky..

The Dr's dates could be off if he's basing how far along your pregnancy 'should be' based on your last period.  You could have ovulated late and only be 5 weeks pregnant or something and the baby just can't be seen by the ultrasound yet.  Your best bet is to go back in a few weeks and have them do another ultrasound.  Also, they may want to keep an eye on your hcg levels by taking blood.

How did the doctor determine you were 7 weeks?  Did he do a blood test or did he just base that off when your last period was?
