Not sure about the whole numbers thing..
But i had subcorionic hematoma all through first trimester with my pregnancy in 2011...terrible terrible bleeding (sometimes only when i wiped some times gashing like a stab wound)
Shes a happy healthy 2.5 yr old now.
Bleeding is a lot more common then women think. We have it drilled into us that any blood in pregnancy is bad and means no hope, which isn't the case.
