In brief: Yes

Heparin, a blood thinner, is used in pregnancy for a number of different conditions.
There is unfractionated Heparin and low-molecular weight heparin(lmwh). Both are given as shots. Neither cross the placenta and do not have any affect on the fetus. Unfractionated Heparin requires more monitoring than lmwh. The blood thinner to avoid in pregnancy is Coumadin (warfarin) which can cause birth defects.

Both unfractionated heparin as well as low molecular weight heparin are safe in pregnancy-- neither pass across the placenta.
