low fetal heart rate

[Stephhfi]

I am currently 7 weeks pregnant and my last vaginal ultrasound detected a fetal heart rate of 65.  The doctor asked if she the u/s tech had a hard time finding the fetus and she said "yes".  At that point she moved it around and got a better image.  I was wondering if when she did the first test if she was not close enough and that is why the heart rate was so low?!  I am on Progestrone twice daily and on bed rest.  Please let me know your thoughts on such a low heart rate.  Do you think the bed rest would slow the fetal heartrate down?

Thanks ,

Do you think the ultrasound could have been off?

Hello,

A slow fetal heart rate at 7wks gestation suggests an increased risk of miscarriage.  I'd recommend repeating the sono in one week.
