Differential diagnosis for bleeding in pregnancy
Uterine bleeding during pregnancy is a common clinical presentation that often necessitates obstetric ultrasound for the assessment of the haemorrhage, and of fetal well being.
The potential causes vary with the stage of gestation.
Bleeding in the first trimester
- subchorionic haemorrhage
- ectopic pregnancy
- gestational trophoblastic disease
- demise of a twin
- implantation bleeding
Bleeding in second and third trimesters
