Doctors wouldn't hide it. That's just not something they do. It's genetic testing, so I don't know how it would be wrong. How do you know the ultrasound only showed the little one you saw?
As for the pap, no they don't cause a miscarriage.
first im sorry for your loss. misscarriages are hard. paps are important and dont cause harm during prenancy and sometimes a larger baby will hide a smaller one and im sure the your doctor did not hide any thing knowingly and misscarriage is more common that alot of women think these things happen in nature to no fault of your own or your doctor
First i'm very sorry for your loss...But like above posters have said, the pap wouldn't be the cause they are done all the time and are important...and I don't see your doctor hiding anything from you, and like the above poster said a lot of the time a larger baby will hide a smaller one...and miscarriage's are very common it's not your fault...Just try to keep your head up in this time...and try not to have negative thoughts of people hiding things from you...
