In brief: Bleeding

Heparin does not cross the placenta so there will be no direct effect on the fetus.
The primary risk for the pregnant mom is bleeding problems for her from the heparin, particularly if she were to suffer from placental related bleeding such as an abruption. An urgent maternal or fetal problem requiring delivery also poses a risk of bleeding if heparinization cannot be reversed before delivery.
