Is it abruptio or placenta previa that bleeds when placenta is low?

In brief: May be both
A previa is usually painless bleeding when the cervix is changing (dilating) causing bleeding from torn vessels being sheared off.
It is a type of abruption although any bleeding from a detaching placenta is strictly called an abruption. These are usually away from the cervix and can be associated with cramping, pain, or heavy bleeding. If you have a previa, let your doc know if you bleed.

In brief: Previa
Previa: Placenta overlies the cervix/birth canal.
Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

In brief: Previa microabruptio
Placenta previa bleeds when microscopic abruptions occur right over your cervix, so the answer to your question is: both.
