How Accurate Are The Results Of Ultrasound During Pregnancy?
My sons ex girlfriend is claiming to be pregnant by my son but everything is adding up to her being a week adead of when the first had sex. So my question is this how accurate are ultrasounds? And can a baby measure 1.1cm with a heartbeat of 134? She said she was 7 weeks by the ultrasound 9 weeks by her LMP and had sex for the first time with my son 6 weeks ago if that helps any? Im really confused can you help me out?

Hi,
Thanks for writing in HCM.
Well, pregnancy has to be calculated from the last menstrual period.
It should never be taken into account the time of having intercourse.
Ultrasound report will not tell the EDD (Expected Date of Delivery) or weeks of pregnancy properly. The variation may be +/- 1 week to 10 days.
But the measurements and other parameters like heart rate are nearly accurate.
Hence, you need to calculate weeks of pregnancy from the date if last menstrual period (LMP).
